Quality Part X LTD Reviews 

Had the car delivered to me in September 2025. Since the warranty expired I have been back and forth to a garage multiple times with engine management light continually coming on - not ideal when my job consists of driving all day. Already had one repair done and looks like I’m going to need hell of a lot more. Angry and sad don’t even come close to it, treated myself to a 2021 car and having more issues than I did with my 2011 car!

I purchased a 2020 Mercedes CLA 180 in November 2025 from the Stevenage dealership (salesman Albi). The car looks great on the surface. I took it for a short 5-minute drive, and it was fine. I asked the dealer about any issues or previous accident and they said no to both. They also insisted that I should buy a warranty and convinced me that it was the right decision. So I purchased one year of warranty. Then it began:

1. The engine's auto shutdown didn't work. This is something that the dealer should have told me - it is the job of the dealership to make sure the car is represented correctly. This issue is caused by fitting a cheap battery to the car. I asked them to fix it using the warranty I purchases and they said the warranty covers everything except the battery.
2. Apple CarPlay does not work. I asked them to get it fixed, and they said they do not work on post-sale fixes over weekends. I rely on my car to commute to work, so I decided not to take the car to them since they are far from where I live, and I have no means of commuting to and from their garage once I drop the car off. It is cheaper for me to just get this fixed at a local garage.
3. After sensing the car had been misrepresented, I had it inspected by a professional mechanic. The front bumper had been welded - meaning the car had been in an accident (contrary to what the salesman told me) and the repair did not include a replacement of the bumper, rather a cheap fix of just welding the bumper. There was aslo signs of paint jobs. This is evidence that the dealer knew about the repair because they made a mistake of not removing the paper tape from the edges of the bumper entirely - so the paint job was recent. They lied to my face, basically.
4. Behind the bumper, there is a front panel that holds the bumper. There is an entire piece missing! It is not essential, but it is clear that they just fixed this car up to sell it for maximum profit.

Totally unreliable, unethical dealership. Do not trust a word they say. They will aslo not accomodate you if you have post-sale issues. You will be left without a car on weekdays if you need anything fixed.

the process of buying the car was great, perfect condition car and lovely sales team. However as stated in other reviews the aftercare for this company is shocking emails are ignored unless you send sharp emails… please ensure all your questions are answered before you leave with the car as getting answers afterwards is near impossible.

Wow - I’m so happy with everything I called this morning spoke to Aleen - I was booked in a few hours later - taken on a test drive with Jon and the car was amazing I’m so happy and also Adam made the finance so easy and fast for me I was out in a 2 hours after driving and waiting for finance to pay out but again I’m so happy.

Picked my car up, as it was late was told all good fresh mot put on it an its been washed.. anyway took it to fuel up an low an behold wasn't even washed dirt an dust everywhere.

So the following day I had it washed which revealed a very poor paint job no rear badges on the boot. Closer look its had the boot, rear bumper, whole passenger side front bumper and front wings and bonnet. A total mess of of a paint job.

I immediately got in touch with this stealership an was told return the car an we will sort out the issues. It's a 4hr round trip for me.

Umm no thanks you should of done the job properly in the first place. An I'd rather you pay the bill at my preferred bodyshop.. sorry we can't and wont do that, we have our own bodyshop. Bodyshop, I can do a better job with a rattle can..

An the best part is they even tried to deny they have sprayed it.. luckily I took screen shots of the listing which clearly showed the rear badges on the vehicle. An they have now deleted all listings

So once I notified them of this they changed there tune. An said we will collect the car, and rectify the paint work.

Still a no from me. Im going to have it sprayed as it should of been sprayed in the first place.. a proper job. So stay well clear from these dodgers

I will be sending them the images of a proper job for there reference

Read the reviews

Friendly staff and very knowledgeable.

Great experience with them.

Thanks

When i brought my MG in November i was given a key without a blade as i got locked out my car the other day and there was no blade in the key , i called up explaining if i had the blade i would of been able to get into my car, i live hour and half away and i couldnt take car to them as i cant get in the car, i had to pay for a locksmiths and i sent the invoice over to the garage to pay this as this is there fault not given me the blade, they have refused now to pay the invoice and flogged me off the professiolism at this business is a joke and i will never ever buy a car of them again, i have also now got a Engine managment light come up on my dashboard with two months of buying the vechicle they are SCAMMERS dont trsut these guys they would sell you ice to the eskimos if they could. bunch of uselss idiots.

Good selection of cars, and seemed to be at pretty fair prices. Service was efficient and helpful, no problems at all. Would recommend.

I had a fantastic experience buying my car from Quality Part X Cars in Stevenage. From the moment I arrived, all the staff were welcoming, friendly, and incredibly helpful—there was nothing they couldn’t assist with. A special mention goes to Chris, who helped me throughout my purchase. I was very undecided about which car to choose, but he took his time, never rushed me, and made sure I found the car that was right for me. He even went above and beyond his working hours to ensure the car was delivered so I could have it the very next day. The prices were amazing, and I’ve had my car for a few days now and absolutely love it. I’ll definitely be recommending these guys to others. Thank you so much Quality Part X - 5 stars was well deserved

Great service, the whole experience was quick and smooth. Love the car. No issues with it so far.

DO NOT BUY FROM THEM!
Reading some of these other reviews, we got off lucky. We had some minor issues with the car after purchase which they did agree to fix. However, after a day off work and a 2 hour drive each way to and from Dunstable they told me they had fixed it. As soon as I get home and plug it in, they have not. Turns out they had just reset it without any form of investigation.
Long story short, it has taken about 3 months to get through this. They held onto the car for several weeks before telling me they couldn't fix it and needed to send it to the mains dealer a month later. Agreed to bring the car back to me and send it to a local dealer instead. Local dealer was brilliant (shout out to Unity Fiat, Leicester), fixed the problems, but now QPX are refusing to pay for half of the work.
I regret having anything to do with this place.

The first vehicle I purchased had an underlying issue that the Quality Part X clearly did not know about, but it was creating numerous issues for me, so I decided to change the vehicle. Klaudia and Omar from after-sales have been highly supportive and have done everything possible while I was experiencing issues with the first car. When I requested a change, Omar spoke to other members of management in a timely fashion, despite it being between the Christmas and New Year period, and they agreed to facilitate the swap of the car.

Upon my second arrival, I was met by friendly staff members, and after checking out a new car, we began sorting out the paperwork. The process was seamless, and I just needed to sit back and relax. Ray (sorry if misspelt) was very effective and transparent, and resolved all the procedural steps to complete the settlement and get a new finance agreement.

I am pleased with the car.

Guys, there are customer-focused and very knowledgeable.

Giving 5 stars.

1 star is too much. Our car broke down after 55 mile on m25, Merceds dealer ship diagnostics discovered 13 fault codes, to engine and drive train, what results always in limp mode, brought the car back to quality partX for repair, they had it for 9 days, just deleted the fault codes done no repairs, used the vehicle 280 miles, transporting people and goods, damage inside and outside vehicle, wheels buckled, chips in the Laqure, rubbish left in car, cigarette ash in car, neither of us smoke, these scumbags are a scandle for the motor trade and has to be stopped. We paid £32,500 and it’s not acceptable we permenantly break down with the car, our car has spent more time in the workshop and on a recovery truck than on the road. All authorities have been informed, all legal and court action in progress. If you go there and buy a car, it’s your own fault.

Really good experience. Staff are really friendly and helpful. Car is running and driving perfectly so far. Wasn’t pressured into buying was allowed to have time to think and consider. After care is also excellent, definitely recommend to future customers who are looking to purchase high quality cars.

Bought a 21 plate bmw 3 series in Nov 2025. Within 5 weeks engine management light came one. Got it checked and it’s an expensive fix £1500.

Tried to contact Faris who dealt with this deal and he does not even bother to send a single reply. Stay as far as you can from these guys !!!! Scammers

Excellent service! I was in communication with Adam and Mo about the car they were very helpful and gave me all the time needed to ensure I was happy with the car. Highly recommend!!

A good used-car buying experience in Stevenage, staff are helpful and friendly, both during enquiries, through buying and in after sales. The car was well prepared for sale, all buying options were explained well so you could make informed decisions. Will recommend to others, thank you

Generally a good experience. The car is great so far and the second one we looked at. Polite staff, didn't feel overly pressured into buying warranty/ add ons and our enquiry about stocking finance was answered quickly. The only problem was the first car had a mechanical issue that wasn't picked up until the day we were viewing and as a result we travelled ~1 hour and were not able to see the car, maybe this could have been checked earlier.

I just bought my first car from Wasi we recieved amazing service and a great deal.

Asked for a holding fee and never returned it. Horrible customer service. Nothing but lies over the phone. Avoid like the plague.
