If you are looking for a BMW I would certainly recommend trying Warren cars. I found them to be very straightforward, honest, knowledgeable and helpful. The 5 series I have just purchased was immaculate and exactly as described and portrayed on the website. The warranty provided appears to be very comprehensive. Part exchange values were also very fair.
On flying down from Scotland to Luton, was greeted by Bill who drove me to the dealership around 40 mins away. On seeing the car I was offered a test drive and explained all the controls of the car, my home address already in the satnav and almost 200 miles of fuel in the tank. Highly professional transaction and Bill is extremely knowledgable on BMW,s, I recommend this dealership to anyone looking for a good quality vehicle and trouble free sale..
John Warren Cars had put all the cars history in the photo adverts which made it easy for me when viewing online. I could not pick the car up immediately and it was held on reserve for a few weeks. Their cars are well stored at their private facility. As we were travelling from Scotland J.W.C. kindly offered to pick us up from Luton airport, which was a great help. The car was just as described and the whole transaction was made simple. The car was also supplied with a warranty which was very welcome.
A good experience from start to finish. The car exceeded expectations and the price was fair. Bill at the Aylesbury location is very knowledgeable and passionate about the cars he sells. I would not hesitate to recommend to my friends and colleagues. BMW 3GT 330D M-Sport with lots of extras.
Was very helpful throughout, he takes his work very seriously and definitely a seller you should trust ... the condition of his cars are in top state and he is very easy to communicate with even though we were in a different country.. we definitely recommend John to anyone interested to buy a car..
Professional and personable service from this dealer with a small but impressive selection of high quality cars. Hassle free process of viewing, test-driving and ultimately purchasing one. Would recommend.
A very pleasant experience from JW. Seemed to have a nice stock of quality cars advertised and priced at what he wants to sell them for. Show room is all in doors, so no wet freezing forecourt. It’s a small business, so no high pressure sales from cheap suits trying to make sales targets. Happy to recommend.
Would definitely recommend John warren cars were really helpful in helping me make the right choice for my first car. They were knowledgeable, provided me with a great quality car and made the whole experience run smoothly.
One very happy customer!
The service I received was nothing but exceptional. The knowledge about BMW really showed which filled me with confidence from the moment I arrived. Everything from initial inspection, test drive and collection was very thorough and hassle free. Highly recommended and a pleasure to do business.
Customer care at its best
Bought a BMW X1 from John Warren in October 2017, and from the start really impressed with the way that they do business. Found that there was a water leak into the rear passenger footwell after around 3 months - just outside their warranty period, but contacted John and he took the car back, got the problem rectified and - no charge. This is what I would call proper customer care and customer service - I have never received this level of service from a main dealer. Thanks John - we would recommend you to anyone looking for a quality car - and quality service.
Excellent service , highly professional.
I found John Warren Cars through Autotrader when searching for a used BMW. Their website was very professional with several images and a comprehensive description of the vehicles that were in stock. On visiting John Warren Cars, the professionalism shone through. The vehicles were stored out of the elements with the addition of dust sheets. The vehicles were extremely well presented. On taking my proposed purchase for a test drive, John was extremely informative, he explained everything I needed to know in an informed and friendly manner. Once I had decided to purchase my used BMW, John ensured the transaction went as smoothly as possible. His efforts meant I was able to collect my new purchase at the earliest opportunity. Truly excellent service
Having scoured the Internet websites “Auto-trader” and “Car Gurus” for a used BMW and getting totally confused!! I decided to ring John
Warren Independent Cars where I had purchased my current BMW 528i Tourer in 2002.
John’s expertise and knowledge of all bmw models soon gave me sound advice as to what model and engine size I should be looking for to replace my 18 year old 528i. His suggestion for a continued BMW driving experience a 530 D SE would be an ideal replacement and explained that one would be available soon and he would contact me again so I could view the vehicle.
Pleased to say I took delivery of the car beautifully prepared and mot’d to John Warren’s high standards. I have not been able to part with my 528i that will now be used for “Dog Walking” and general gardening duties.
Highly recommend you give John a ring like I did but perhaps Don’t leave it 15 Years !!
John C, Essex
I got to know about John from a friend who bought a 325 from John 13 years ago...he still has it and it has never gone wrong..I intermittently perused Johns website, and when the car I wanted finally appeared, I bought it 18 months ago...the car preparation was immaculate, and it looked as new, inside and out. I had confidence that John only supplies the best cars, and that's how it's turned out..just a great car which has been impeccably reliable.. I can highly recommend John if you're looking for a first class used BMW
Hi John, It may have taken me around a year to take the plunge, but it was worth the wait! My new car is perfect, it drives beautifully and the price has not taken too much toll on my finances.
Dealing with yourself has been a pleasure. It's great to get experienced and honest advice where, at times, the industry gives unnecessary sales spiel. To be able to discuss requirements and then let you get on with it is exactly what I need and exactly what I would recommend to everyone if they want a BMW.
It's a great shame that I haven't bought a car from you before, but I certainly look forward to doing so again in a few years time. Many thanks once again. All the best
Hi John, Just to say thank you for your help buying a car. I am thrilled with my new BMW Convertible and It is a pleasure to drive. Most of all, it is so good to be able to buy from someone I trust. This is the third car I have bought from you, and I have peace of mind knowing that I have good value for my money: A reliable car from a trustworthy dealer.
We have been very happy with our BMW 3 Series Sport purchased from John Warren Cars, in November 2016.
We had been looking for a 3 Series for some time, and having seen lots of expensive “below par” models in car supermarkets, a 3 Series at John Warren Cars caught our eye. It looked good in the photo’s posted on the website, and we were not disappointed. It was in excellent condition and as good as any for sale at BMW. John conducted himself in a pleasant informal way and was very knowledgeable, making the buying experience very relaxed and non preasured.
We would thoroughly recommend John Warren Cars if you are looking for a quality used BMW at a competitive price.

I have never been a BMW owner and after some research into my next car a BMW Z4 beckoned. Having looked around I was most fortunate to drop onto John Warren Cars. Straight away the cars looked first class and keen on pricing. A phone call to a most pleasant man who, on a bank holiday, agreed to meet me (I live on the south coast) I popped over to see the car. Well… stunning…. Absolutely perfect….and in my favourite colour ‘bright red’ A thorough test drive and it had to be mine. A very fair deal on my ‘trade in’ and it was back to the cast for me. Within the week I picked it up .. no sweat, no hassle, my Z4 car awaited .. gleaming and after a very thorough handover I had a dream drive home. I have no hesitation in recommending John Warren Cars if you are looking for that special car and a fabulous dealer. My Z4 and I are going to have some great adventures together… Thank you
Having owned the same 320d SE Touring for the past eleven years, I’d been looking for a while for a replacement. Having spotted a low mileage and very clean example I contacted John and made arrangements to travel up from Devon. I was collected from Knebworth station and taken to the workshop where I knew immediately I’d found the right car. For a 2005 car it was in better condition than many ten years younger. This was partly due to the comprehensive valet but also testament to her previous owners who has obviously taken great care with her appearance and maintenance. I was relieved to see Continentals on each corner as you can tell a lot about a car owner from their tyre choice. A decent test drive was followed by the paperwork – all painless. She covered the 250 miles home without missing a beat and although at first I felt a little disloyal to my old trusted and faithful friend, I quickly fell for this new set of wheels and I’m sure we are going to have a very happy future.
Just a quick email to say thank you for setting me up with an absolute stunning car. I dont think I will ever get bored of the sound or the acceleration it, for me, is unbelieveable! Even sat in the M1 traffic i had a huge grin on my face all the way back to sunny Yorkshire. Also, thanks for taking the time to talk me through everything it has to offer, a massive help.
Why oh why did I not come to John first? I had been in the market to upgrade my car (2005 320d Touring) for a while and had visited the local BMW and Audi franchised main dealers. The service and attention I received from them was patchy to say the least. I took a look at the cars on John’s website and spotted a 520d SE saloon that I liked and made an appointment to view the next day. The car was on display at his Codicote premises and was exactly as described. I was able to take my time to look it over as John creates a very relaxed and non-pressurized environment. He is extremely knowledgeable about the BMW range and answered any questions I had. I took the car for a reasonably long test drive and agreed to buy it. There was no negotiation needed, I had researched car prices and knew that the asking price was extremely competitive (believe me, this is very unusual). John arranged for a full pre-delivery inspection and MOT, which included new front brake pads. This was all part of the service. I collected the car a few days after and John took me through all of the features of the car before I left including pairing my phone for me.
I am delighted with my stunning, metallic black 5 series. Thank you John. I will come to you first next time.
Travelling from Essex and not being an expert in car purchasing I had a few questions on the BMW 530D which I wanted to be clear on before I made the journey. John was very prompt in answering a number of my emails and calls before I came to see the vehicle. It was a very pleasing viewing experience with no pushy sales at all. John gave me an honest price for my vehicle which I wanted to PX and I left the deposit on the first visit. The car speaks for itself but the honesty and trust developed with John really gave me confidence in parting with the 15k+ for the vehicle with John Warren Cars. Arriving on the collection day the car was ready in immaculate condition and John took his time in going through everything with me making this a great purchasing experience, The car was in amazing condition and the drive totally amazing. A big thank you to John from another very satisfied customer. I am sure I will be back when I am ready to purchase again and I have already recommended John Warren Cars to friends and family.
I just wanted to drop you a note to say a huge thank you for making car
buying a genuine pleasure.
Nowadays, sadly, buying a car can be a stressful event with very variable levels of customer service. However I can honestly say that the customer service experienced with yourself at John Warren Cars was outstanding from start to end.
The transparency you provided of the car history, the test drive, going out of your way to deliver the car and spending the time to introduce me to all the features was far above any other car purchase I have experienced and really appreciated.
I will certainly recommend you to friends and family and get in touch when it's time to change cars again.
Alex James, Chepstow, Monmouthshire
I've been looking for a BMW 3 series touring for some time, and eventually spotted one I liked the look of at John Warren Cars. But it was at their Stevenage premises, some way for me to go for a test drive. No problem - Bill Warren agreed that he would transport the car over to their Aylesbury depot. The car was (is) a delight - in immaculate condition. Bill was extremely courteous; and helpful in going through all the controls and features when I went back to conclude the deal.
Been driving the car for a few weeks now in various conditions and it's a joy. So thank you to Bill and John Warren Cars - dealing with someone who clearly has a real passion for the cars he sells makes the transaction a very positive experience
Kevin Kavanagh, Witney Oxon
Bought my BMW330d from John Warren in May 2015.
I live in Bristol so it was a bit of a trek up to Stevenage but it was certainly worth it. The car was exactly as described on the website and was very well presented. John had also MOT'd the car for me prior to my arrival. After a fairly short test drive I knew the car was right. John had agreed a P/X price for my old car over the phone and that was the figure he gave me. Three months down the line I've had no problems and she drives beautifully.
John was a pleasure to deal with; I would thoroughly recommend him and I would certainly buy from him again.
Having now bought four vehicles from Bill Warren over the last 16 years, I can truly say he offers excellent advice and always has time to explain in details every aspect of a cars equipment. In particular one is never hurried to make a decision, and all the cars are immaculately presented. Bill Warren's courteous manner is particularly appreciated.
I heartily recommend this company to anyone wishing to purchase a vehicle.
Dr Mervyn Pichel. Oxford
Due to my company car lease running out, I decided that I would take the cash allowance and buy something that I’d always desired– a 5 series BMW M-Sport Tourer.
After searching websites for many weeks and looking at various BMWs, Auto Trader led me to a stunning looking model, 2011 Titanium Silver Metallic with black leather interior, 19inch Alloys, full BMW service history and one owner, advertised by John Warren Cars.
A quick phone call and I was on the way to view at his Codicote premises. First thing that struck me on entering the unit was how organised John was, how tidy the premises were and how every car was protected by individual dustcovers, a lovely touch.
To say John is knowledgeable about his cars is an understatement; he knows everything about each model, something that can only be obtained from years of experience, and is pleasant and honest in his sales manner, never forcible (I’ve worked in sales for many years and can quickly spot a chancer).
Test drive over I was sold, John and I came to an agreement and the deal was done. That was six months ago, the car hasn’t missed a beat and draws admiring glances wherever I travel to.
Thank you, John – you’ve put the enjoyment back into my driving!
Darrell Carter, Ware, Hertfordshire
Hi Bill. I would just like to extend my thanks to you again for selling an honest car at a sensible price, your a rare breed in the motor trade, and it was a real pleasure to meet someone who appreciates the cars in the same way that I do.
Adam Bayliss, Tamworth
Kate and I brought a 2010 BMW 318d through John Warren Cars in August 2014.
Having looked extensively for this model with specific additional extras; we found what appeared to be our ideal car advertised on the John Warren website. When we arrived; we found the car exactly as described, in excellent condition and thoroughly cleaned.
We felt very comfortable buying from John due to his honesty and transparency; and have no hesitation in recommending his services. To date, (January 2015), there have been absolutely no problems and we remain incredibly pleased with our new BMW.
I've recently bought my third BMW from John, and I'm very happy indeed to endorse him and his family's business.
I first had a 328i M sport auto saloon from him in 2002 which I kept for 4 years, followed by a 530i with the same spec, which I traded with him recently for a 2011 330d Touring. Throughout this 12 years of experience I've never had a significant problem with any of the cars, which have just required routine servicing and the sort of standard replacements that are expected over this sort of prolonged period and significant mileage - brake disks, calipers and the like.
I'm sure this good experience is largely down to John's expertise at sourcing good vehicles through his trade connections and preparing them well. He is highly professional to deal with, and you are given plenty of time and support to make the right decision. You are put under absolutely no pressure to buy or sell and he's a mine of useful information on the BMW marque. The company is widely recommended on independent BMW forums and this sort of endorsement doesn't come easily: it has been earned through years of straight practice.
I would very happily deal with them again.
Dr Mark Farrington, Cambridge
I bought my dream car from JW in April 2005, a blue, with cream leather, BMW 530d M Sport. 3 years old with full history and 60,000 miles on the clock. I had searched hard for a good one and here it was. I couldnt have been more thrilled when I drove away from the rural farm location where JW has his amazingly neat and tidy showroom with various sparkling nearly new BMW’s all smelling of fresh AutoGlym and individually covered with dust sheets.
My ‘ultimate driving machine’ was a delight ....until Boxing Day when out of the blue it failed to start on the forecourt of a garage after filling up with diesel. It turned out that the main ECU had a mysterious fault, so I rang JW who promptly arranged for it to be transported back to his service agent where a new ECU was fitted.
I drove it virtually every day for the next 9 years and when the mileage got to 250,000 (yes...a quarter of a million !!) I sadly decided in April 2014 it was time to change. I set my sights on a 325d or 330d and saw that JW’s web site was displaying a mint 3 year old 330d M Sport coupe.
A quick phone call renewed our acquaintance and JW kindly agreed to meet me for a test drive on a Sunday morning. So, 9 years on, another trip to the farm showroom at Codicote where a spotless grey 330d was uncovered & awaiting a test drive. It was perfect, only 48,000 on the clock, full history again and went like a dream. But for this purchase I was going to need some finance, no problem, JW now offers a straightforward facility, so after deciding how much and for how long, and throwing in an extra 3 months on the warranty, we had a deal.
When I drove away in my new 330d M sport coupe I thought back to the fantastic blue 530d and wondered if this one will reach a quarter of a million. So far so good.
Brin Hughes, Newmarket
I have purchased cars from John Warren for over 30 years, most recently in September I bought a BMW 320 MSport Touring. I was undecided on exactly which car I was interested in and spent a whole afternoon with John looking at his stock and test drove several cars until I chose the 320 Touring.
The whole transaction was completed within just a few days and I was able to collect the car in time for a week’s driving along the south coast. Along the way unfortunately I had a warning advice show on the computer indicating low oil pressure, on restarting the car the warning went off and everything was again normal, I called John for advice and he suggested that to be certain there was no further problem he would have the car inspected and the oil pressure sensor changed as a guarantee. This was carried out within a couple of days of my return under warranty.
The service, advice and help from John Warren has been first class and the 320 Touring is the most enjoyable car I have ever driven.
Steve Walsh, Letchworth Garden City
I have been a customer of John Warren Cars for 22 years and have been quite happy to deal solely with John Warren throughout that time. My first 'Car Purchase' from John Warren Cars was completed in 1992 and since then I have exchanged several cars as newer models have become available. I have always been satisfied by the way in which each transaction was handled and concluded.
John Warren is very discerning when acquiring cars for his stock of vehicles and the pedigree of each vehicle is painstakingly checked; particularly it's Mechanical Service History, which is very important. It is very re-assuring to know that all of their vehicles for sale have been earlier subjected to and have met John Warren's rigorous standards.
I have always received and enjoyed excellent Customer Service from John Warren Cars which is a distinctive hallmark of their operational style with the added bonus of many consecutive years of trouble free motoring.
This is why I have been quite happy to recommend John Warren Cars to my friends and relatives over the last 20+ years.
Brian Peacock, Hatfield
We arranged an appointment to view a BMW 320d. When we arrived Bill was waiting for us and the car had been moved outside ready for us to view. We spent around 1.5 hours with Bill, including a long test drive, and at no point did we feel rushed or pressured. Bill answered all our questions and agreed to take our old BMW in exchange. The paperwork was completed with ease and we are now enjoying our new car.
Paul Helbrough, Rickmansworth
Having just bought a BMW 520d from Independent BMW, I found the handling of the sale excellent. John, with whom I dealt with from the start, knew the car down to the last detail. I was shown all relevant documents including all servicing bills. The test drive was not hurried and there was no feeling of pressure to buy - something one tends to suffer in most car sales.
All the cars seen looked immaculate. John had the car have a pre delivery check, which was reassuring. The car itself has been faultless. I had a call from John some weeks later to check - again, something one doesn't get with most car sales. I would unreservedly recommend Independent BMW.
Dr Khan, St. Albans
My wife Alison and I have been buying cars from John Warren for about 16 years. Over that time we have had 6 cars between us and have never been disappointed with the quality and reliability of the cars we have purchased. We have always had absolute faith in John and we have never had cause todoubt his integrity and honesty. He specialises in high specification used BMWs and I wouldn't dream of buying a BMW anywhere else.
The after sales service has always been excellent too and John really cares about the cars he sells and the service he offers subsequently. It is rare for car dealers to inspire confidence and customer loyalty but this is precisely what John Warren has achieved and I would have no hesitation in recommending anyone looking for a used BMW to look no further than John Warren Cars.
