What customers say

Based on genuine customer reviews

Vehicle repairs, servicing, tyres, MOT testing and diagnostics are the services that customers bring their cars in for, and the feedback about how that work is carried out is consistently positive. Various customers describe being kept informed throughout, with photographs of faults, computer diagnostics and written quotes sent before any work is authorised, and an observation shared by more than one reviewer is that nothing is done without permission and the cost explained first.

Jason is named repeatedly for honest diagnoses and clear explanations, while Keira is mentioned for handling parts orders and bookings with clear communication. More than one review highlights the friendly and helpful manner of the team, the care taken to explain faults in plain terms and the quality of the finished result, whether that involves tyres and pressure monitors, a service and MOT or more involved engine work such as a Vanos unit and timing issues.

Tidiness and a welcoming reception area also feature, along with the speed of getting vehicles booked in and turned around, and the fairness of the prices quoted for parts and labour. Owners of older and problematic cars describe being spared a scrap decision after difficult faults were traced and rectified, and long-standing customers return because they trust the advice given.

Really disappointing experience.. I took my car to RJ Mechanics in Bletchley after the engine warning light came on and I noticed a strange rattling noise when accelerating. I was told they would carry out a diagnostic check and contact me once they had worked out what was wrong. Unfortunately, the customer service was just as disappointing as the repair. When I first arrived, their was a young girl working at the front desk was quite rude and seemed irritated when I asked questions about how long the repair would take. At one point, she was swearing while speaking to me, which I found completely inappropriate and unprofessional. I was eventually told that an engine component needed replacing. I agreed to the repair and paid for the work, but after collecting the car, the warning light came back on later that day and the rattling noise was still there. When I contacted the garage about it, I was told I would need to bring the car back in and may have to pay for further work. I was frustrated because I had already paid for the original repair and expected the problem to be resolved. Overall, I was really unhappy with the experience, particularly the lack of communication and the way I was spoken to at the front desk. I wouldn’t personally return to this garage.

I was recommended RJ Mechanics by a friend and I can see why. Incredibly helpful right from the off, booking me in quickly and working around my availability. Jason gave me an honest diagnosis of the issue my car was having and ensured I got the best parts for a very good price. Keira handled ordering the parts, booking me in for the work and plenty of clear and easy communication leading up to the work being done. Really happy with the whole process and will be recommending to others. Thank you to Jason Keira and all the RJ team.

Absolutely outstanding service from R J Mechanics. I called first thing this morning to ask about an air conditioning regas, and they kindly said I could pop straight in and they would do it while I waited. The whole process was quick, professional and hassle-free. They also charged less than both Halfords and the other local garages I contacted, all of which couldn't fit me in for around three weeks. The team were friendly, honest and explained everything clearly. They even provided a printout showing the amount of refrigerant recovered and the recharge carried out, which I really appreciated. It's refreshing to find a local garage that offers excellent customer service, fair pricing and doesn't keep you waiting for weeks. I wouldn't hesitate to recommend R J Mechanics and will definitely be returning for future servicing and repairs. Thank you again!

Highly recommend RJ MECHANICS, had a lot of work done on my car lately. Thanx to RJ MECHANICS, my car is all fixed. They found the issues, and then kept in contact. They didn't do any work on my car without permission, and they inform you with cost. Then you the customer makes the decision. Many Thanx RJ MECHANICS for all that you have done.
