I took the family car in for an MOT here. I found the staff very efficient, knowledgeable and courteous. The turnaround was rapid and yet the attention to detail was good. I will certainly be going back!

Huge thank you to the awesome Cornerstone Autos who went out of their way save our family holiday from disaster! We had an issue with the brakes on our car and the advice and attention we received was second to none and we were back on the road the same day. The customer service was excellent: a waiting room to keep cool in, a prompt assessment with options clearly explained, a courtesy car while the work was given priority, and a genuine effort to minimise the impact, keep the costs down and to get us back on our way. Cornerstone Autos, you rock!

I have been servicing and repairing my Mercedes cars with Cornerstone for a number of years now and highly recommend them. They always provide a professional and friendly service and in my opinion provide excellent value for money.

I have used many garages and mechanics over the years. I would rate Cornerstone as number 1. No problem too small or big great service and quick turnaround
