“All the guys there have looked after my car for years. They are a garage that you can trust 100%. Thank you for yesterday.”

“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 they are in need and unable to leave their home environment. Not only did A1 fit me in for an MOT with less than 24 hours notice, they did it for FREE!! My car was sanitised before and after the MOT and tyres were also provided at cost price!!! This generosity is fantastic and I can now undertake my stressful job safely out on the road getting to patients all over the country! Thank you A1 diagnostics. Would 100% recommend!
