National Vehicle Suppliers Ltd Reviews 

Mark was communicative and honest throughout the whole process. He drove in the worst traffic to deliver our car and we couldn’t be more grateful to him.

I have bought 2 minis for myself and daughter from Mark and have experienced excellent service throughout. After developing a fault (it is an old car), Mark picked up the car and swiftly resolved it.
I recommend him to friends and will be returning to purchase a third car for other daughter. Thank you.

Do not just rely on the presentation of the stock yard or yard appointments. Please check public legal databases and Companies House before doing business with this dealer.

The director, Mark Barclay, has historical convictions and prison sentences for motor trade fraud in the Swindon area, alongside multiple outstanding CCJs for owing money to customers in the past, during 2025 as well as recent county court judgments made this year in 2026.

Protect your hard-earned money and research the director's track record first.

We purchased a vehicle from this dealership in March. Initially, the service was excellent: quick responses, a smooth sales process, and prompt delivery. Unfortunately, everything changed once the first problem with the vehicle arose.

When we reported the issue, it took days of repeated phone calls and messages to arrange collection of the vehicle. Eventually, it was collected and replaced with a courtesy car.
However, we later discovered that the courtesy vehicle had no valid MOT, tax, or insurance. We only found this by checking online ourselves. Customers should be aware that, had we been stopped by the police, we could have faced the consequences despite being unaware of the situation.

Our vehicle was away for over a week, during which time we had to pay for a hire car ourselves. When the vehicle was eventually returned, the same fault—a faulty gearbox—reappeared, suggesting that no effective or lasting repair had been carried out.

We reported the recurring fault almost two weeks ago and are still waiting for a collection date from Mark.

Communication throughout this process has been extremely poor.

Following advice from Citizens Advice, we understand that if a repair attempt fails and the same fault reoccurs, consumers may have the right to reject the vehicle and seek a refund. We requested this resolution, but Mark refused without providing any explanation.

Dealing with Mark has been incredibly frustrating. Communication has been difficult throughout, and he even blocked my partner's number, preventing her from contacting him to discuss a resolution.

The vehicle was sold with a six-month warranty, but our experience has been one of delays, poor communication, and a lack of accountability. We have spent months trying to resolve an issue that should have been dealt with properly from the outset.

It's a real shame, as the experience started so positively. Unfortunately, the after-sales service has been deeply disappointing, and based on our experience, we would not recommend this dealership.

Buyers beware.

At first, all appeared well. Brought a Ford Mondeo for £5595 in September 2025 and drove really well. A month in, the gearbox gave up on me, contacted Mark and he took the car back and fixed. 2 weeks later the turbo then had an issue, mark fixed again and then January 2026, the gearbox that had been replaced broke again. Mark took the car back but midway through March I still had no car and Mark would not pay the money back but offered me cash and older car with nearly double the mileage on it and I would have been out of pocket.

Decided to take further action against National Vehicle Supplier through small claims court and now enforced a CCJ as Mark did not respond to any letters.

Although Mark & NVS appear helpful, and granted, initially he was very helpful, multiple false promises and no urgency.

I would avoid like the plague!!

I recently brought a car from mark, it was for my mum, the car was delivered by mark, he arrived on time and all was as shown in the add, he walked us around the car and showed us everything was in working order and was happy for my mechanic to have a look.
Iv had the car about a month now and had no issues what so ever but he did offer me a warranty with the car for peace of mind.
Lovely man was happy to answer all our questions
Brilliant service, would use again

Used this company for the first time..and would definitely use again..everything was straight forward..brought the car to my house (foc) and even went out of his way to put some diesal in it..so definitely 10 /10 al round..ps the car looks like new

Excellent experience with Mark, made the car buying experience easy for me and delivered straight to my door. Car was in very good condition and has been very reliable for me

Photos and car discussed on the phone was different in person
The car pictures have absolutely no damage at all, drove over 120 miles to a car that wasn’t clean, had rubbish in the back and had significant damage to the front, the photo of the car online must either be edited or false, before I left mark said on the phone it was a lovely car with nothing wrong with it!
upon arriving I was given another address a further 12 minutes away to where the car was
Very disappointing
DO NOT RECOMMEND IF YOU HAVE TO DRIVE A FAIR WAY

Reviewed previously, and just wanted to reiterate the shocking service and aftermath received.

Still in the middle of taking further action against this company 👍

My experience with Mark at NVS was excellent and I honestly cannot praise him highly enough. He went out of his way many times to provide me with great service, including personal delivery out-of-hours, and at all times was friendly, personable and kind.

I bought a lovely car from him that was in great condition, but it developed a serious fault within the warranty period and it was unfortunately written off. Even though it was not directly Mark’s fault, he offered to find me a replacement and provided a great courtesy car while he was looking to help me with getting to work, appointments etc. Then, after a couple of weeks without finding a car to meet my specifications, Mark happily provided an immediate refund.

Overall I received great customer service and would recommend NVS to anyone looking to purchase a car.

I had a great experience purchasing my van, thanks to Mark. He was always available at the end of the phone, no matter the time, and answered every question I had with patience and clarity. He made the whole process smooth, straightforward, and stress-free. The level of service was outstanding, and I couldn’t be happier. Highly recommend

Thanks for my new ride! 🚘🤩

Best car by experience. Even delivered the car at no extra cost thanks again and will definitely recommend

Fast to find a petrol station when my tank was blinking red on the motorway

• “One of the easiest and most pleasant car-buying experiences I’ve had.”

Brilliant company so easy to deal with vehicle just a described couldn’t fault them really!!

I purchased a VW Polo from NVS on 15/11/25. The car had a fault with the air conditioning and heating system which Mr. Barclay wasn't aware of. I bought it in a rush and in good faith. Mr.Barclay told me to fix it and he would reimburse me the money. He didn't want me to do it through the Pinnacle Warranties because of the paperwork. I naively did it. After lots of text messages, calls and emails, he hasn't reimbursed me the money. I tried to claim the money from the warranty but they don't pay back for the job done. He told me that he wanted to help me and that he would take the car and fix it but he hasn't done it. He also told me to use the warranty because the big fault hasn't been sorted yet. It is the end of February 2026 and still no news from him! He is ignoring my emails hoping the problems will disappear. Beware of this unscrupulous trader that the only thing he cares about is profiteering!

Really happy with my new car – smooth drive, comfortable, and looks great. Runs perfectly. Definitely a great purchase, thanks to Mark!

Mark is a true gentleman of integrity. Having bought a lovely Polo VW from Mark NVS I had a few issues with a boot lock mechanism & the auto-release petrol flap. Mark swiftly & effectively resolved the issues & even covered the cost as it was within the 6 month Warranty. I'm a very happy customer & am sure you will be too if you buy through NVS.
