REPLACEMENTS

I was devastated when my BMW's timing chain snapped. I thought the car was finished. Grays Automotive gave me honest advice, a fair price, and rebuilt the engine to perfection. Two years later, it's still running like a dream. I can't thank them enough.

Daniel Kullins Engine Rebuild

Our business relies on our Ford Transit van. When the head gasket blew, we needed it fixed fast. Grays Automotive fast-tracked the repair, kept us updated every day, and had us back on the road in 72 hours. They saved our business.

Mark Saunders Head Gasket Replacement

My Vauxhall Astra had an intermittent engine fault that three other garages couldn't fix. Grays Automotive diagnosed it in hours, fixed it the next day, and the price was very reasonable. Finally, a garage I can trust.
