Joe managed to book my car in straight away and carried out a really thorough inspection before purchase. He even sent me a detailed video of the underside (something I’d never normally get to see), talking me through everything clearly and in a way I could understand. He also gave it an extensive test drive and ran full diagnostics to check for any hidden issues. The communication was outstanding, the service above and beyond, and the pricing very fair. An honest, professional garage I’d recommend to absolutely everyone!Posted on Tomos Gwyn2025-08-30Trustindex verifies that the original source of the review is Google.

I recently used the garage for a clutch replacement. Joe is a courteous, friendly and very knowledgeable mechanic. He explained the problem to me thoroughly, setting-out details of the work to be done, together with a cost estimate (which was a really accurate prediction). The work was carried quickly and efficiently. A major, positive service provided in the Cardiff area is that a customer’s car is picked up from their home and returned when work on the car is completed. What a bonus that is!!
