National Vehicle Suppliers Ltd Avis 

Really good customer service from mark, i test drove a mini and bought the car and got it delivered today

Very helpful and willing to help in any way possible.

I recently bought my Honda Jazz from Nationwide vehicle sales and the entire experience was outstanding!
​The team was extremely professional, helpful, and made the whole process smooth and hassle-free from start to finish. Special thanks to Mark for providing exceptional customer service and guiding me through everything.
​The car is in perfect condition, and I couldn't be happier with my purchase. I highly recommend Nationwide vehicle sales to anyone looking for a great car and top-notch service!"

Absolutely brilliant service from start to finish! I saw the car online and Mark couldn’t have been more helpful, he offered to bring it straight to my home so I could view and test drive it, and he was nothing but friendly, informative and honest. Messaging was always quick and replies came instantly. A few days after getting the car, the battery went and Mark didn’t hesitate at all. He offered to sort it and pay for everything straight away. He picked up the car first thing, made the repairs, and dropped the car back to me the following morning, keeping me informed throughout! I would 100% recommend to anyone looking to buy a car!

Good communication from start to finish.
No nadty surprises, vehicle even better than described.
Mark was very helpful and a treat to do business with.

I can’t recommend NVS enough, especially Mark and Mike, who gave me such fantastic service when I purchased my first car a Kia Rio after recently passing my driving test.
From the moment I arrived, they were both incredibly helpful, friendly and patient. Both mark and Mike took the time to show me the car properly, answer all of my questions and let me take it for a test drive without making me feel rushed or pressured in any way.

As a first time car buyer and newly qualified driver, I really appreciated how patient and understanding they were throughout the whole process. They made what could have been quite a stressful experience feel really easy and enjoyable.

I’m absolutely delighted with my Kia Rio and so grateful to Mark and Mike for making buying my first car such a positive experience. Thank you both for your brilliant customer service! 🚗😊
Would definitely recommend NVS to anyone looking for a car.

I would entirely echo the words of others on here.
Helpful. Friendly. Informative. All the good things. Took many calls/questions and cheerily answered them all. A very nice car purchase experience - highly recommend. Thanks very much Mark.

Anybody looking for the best deals on second hand cars this is the best place to start, the customer service is second to none,I met up with mike and gave him an idea on what I was looking for and how much I had to spend and within less than a week he's got three cars for me to pick from and that's impressive then put mike's friendly nature and he is really easy to work with and he keeps you well informed and updated throughout the whole process, I will be a repeat customer without a doubt.
Thanks again Mike your a legend.

Delivery Service is brilliant, helpful all the way through, thanks!

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.
