What our customers think about our services

We have hundreds if not thousands of customers that have been coming back for car services over the last 20 years. Here are two customers who have given us 5 star reviews.

“I visited many garages in and around Cardiff leaving disappointed on many occasions as every garage said they could not help with the modification on my Jaguar XKR. I decided to try and seek out one last garage and thankfully this garage was A1 Diagnostics. From the word go I knew I had found a fantastic garage as everything I mentioned I wanted done to my Jag they said YES THEY CAN DO. A fantastic positive attitude and solution to every given problem! Thank you A1 Diagnostics I 100% recommend this garage”

"I attended A1 today for an MOT on my car. I’m a District Nurse and in need of my car to attend to patients when their in need and unable to leave their home. Not only did A1 fit me in for an MOT with less than 24hours notice, my car was also sanitised before and after the MOT. My tyres were also provided at cost price!!! This generosity is fantastic and I now can undertake my currently stressful job nursing the countries most vulnerable adults “legally”! Thank you A1 diagnostics. Would 100% recommend this garage."
