I bought a van off Jonathan in August, buying process was smooth and I got a great trade in price. they provided a 3 month engine and gearbox warranty which was honored in my case with a glowplug issue. They also helped out with some out of warranty repairs. Overall good experiences with Jonathan and Brian, very reasonable.

I bought a car a car off Jonathan O'Brian car sales back in April. Now I seen the car on donedeal but was receiving radiation treatment at the time so I couldn't view the car. I made contact with the garage asked a few questions got a video of the car and got it dropped to my house. The cars a 2009 so its old. Bar a few wear and tear things for it's age the car is in great condition. I took a real gamble buying off them and im glad I did. It all worked out in the end. I love the car. I paid a deposit for the car we agreed on a day and he texted me the on the day a time to expect it. Serviced and all. Im very happy with it 5 months later.

If I could give a negative rating, I would. I purchased a 2020 Vauxhall Insignia from this dealership  in July 2024. The buying process was smooth, and the car seemed fine initially. Unfortunately, within a year, I experienced serious mechanical issues that led to significant repair costs and time without a car. When I contacted the dealer for advice, I didn’t receive the level of support I had hoped for. While the car is now back on the road, further problems have arisen, which has been very disappointing. In hindsight, I would suggest anyone buying any used car  to check the service history carefully and consider an independent inspection before purchase.

08/01/2026 update on the Dealership reply to my review -
Thank you for sharing these recommendations; we agree that timely servicing and addressing warning lights are essential for vehicle safety. However, we would like to clarify that in this case, the implication that the car was driven while ignoring a warning light or that servicing was neglected is incorrect. The vehicle had not yet reached the dealership’s recommended date or mileage for servicing, and we have photographic proof to confirm this. Furthermore, there were no red warning lights present at any time , again we have photographic proof to confirm this so any suggestion to the contrary is hearsay.  Additionally, the dealership’s inference regarding my driving habits as careless is also hearsay as they have no knowledge of my driving history. With relation to - "When a contribution request is denied without proof just make up a story and blame the garage." - Your comment is completely incorrect.
Nothing in my review was fabricated. I have substantial, documented evidence to support every part of my review — including 2  independent mechanics having inspected the car and confirming the faults, timelines, photographs, and all correspondence.
My review reflects verifiable facts, not stories, and I stand fully over everything I stated.

A family member bought a car here in December. It had a DPF issue with the car. They told us it was a faulty sensor. They said they would sort it before we collect it. We had the car less than a week or two and DPF light came on. They took it back 3 times to fix the issue. Every time we got it back the light was back on within a week. We brought it to our local mechanic who said the DPF needed to be replaced. They gave the same excuse that i see in these reviews that it’s a used car and this is basically what you get with used cars, but you shouldn't sell cars with faulty DPFs. Very dishonest and just bad business.
The DPF issue was never resolved and we were giving the run for months on end. No car or replacement for months. These are not good to do business with.

Before I start I used to race cars so I have all the equipment and diagnostic tools and can fix most problems myself. I bought a car from this business from the moment I drove the car home problem after problem kept coming up. The 3 month warranty they gave didn’t cover much. I notified them of all the problems I had to return the car to them as there was a dangerous vibration in the braking system, diesel fumes coming into the car, radio lcd faded after driving, fault codes relating to the turbo came up and car lost all power, sensor fault on the passenger seat belt so when I test drove the car all seat belts were connected to the buckle which I found strange. When it’s not clicked in there is a beeping sound which lasts a long time so I have to have it connected all the time as it thinks someone is sitting there. When I brought the car back they replaced the radio, which knocked out my parking sensors, they charged me €140 for bushes which they said was the cause of the vibration it’s wasn’t ! Turns out the brake discs are warped and need replacing. The car has seat belt extenders which are meant to bring the seat belt to you because it’s a coupe and they are very far back neither of these work. I would strongly recommend avoiding this business at all costs they do minimal work to cars they sell and even after bringing it back and paying to have it fixed it didn’t solve the problems. Was offered a refund but I just took it to another dealer who actually know what they are doing and got everything fixed so was about an extra €700 on top of the €4640 already paid. This review I posted here as the reviews on their website are not real reviews. Read their terms and conditions and it will tell you they reserve the right to change or alter any reviews posted. Thanks for reading and hope it saves you from buying from these guys.
