We are going to keep showing you our five-star reviews received at out award winning garage pictured below. Here are three of our five-star Google reviews.

“Top class people work here, very friendly. They installed a clutch whilst I was stranded, and done it in 2 days. 10/10 will come here again.” “I had an issue with my Mercedes. The dash lights were coming on nonstop. I went to the Mercedes dealer and they could not find the problem. Went to A1 Diagnostics and they found the problem within the first few hours! The staff were incredible, and the customer service is second to none. Rishi and the team really helped me. Will be recommending A1 to all my friends and family. 5-star service.” “I had an engine problem with my Mini Countryman. A1 diagnostics fitted a brand-new engine including a 1 year warranty. Truly a great garage and team, they gave me regular updates on the progress of the car. Fitted the engine within a day, the car is perfect and runs like a new car with no issues at all. I’ve used lots of different garages for services. But I’ve got to say this is the best garage we’ve been to. And my whole family will be using them in the future. I’m also going to tell my friend about A1 Diagnostics. Thank you to the owner and his team.” These are just three five-star reviews.
