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!!

Transmission fluid helps your transmission carry out its important function within your vehicle. It lubricates the moving parts, reduces friction and heat and aids a smooth transition between gears.
Over time, this fluid loses its effectiveness due to persistent exposure to debris and dust, rendering it less effective in performing its role. This heightens the risk of overheating, rough gear shifts, and can even lead to complete gearbox failure.
However, there’s no need to panic. A routine fluid change will ensure the fluid performs its role and continues to help protect your vehicle from costly repairs down the line.
A timely automatic transmission fluid replacement or manual transmission fluid change keeps your vehicle running reliably and protects you from expensive repairs down the road.
