Our reputation has been built on our ability to supply, fit, repair and rebuild engines and gearboxes at affordable prices quickly and reliably. We offer engine and gearbox services for a huge range of vehicles especially German manufactured vehicles like BMW, Mercedes, Bosch, Audi and Volkswagen from our garage workshop pictured below.


As a truly independent vehicle servicing company, we are free to focus on supplying the best quality parts, at the most affordable prices, all backed by the highest levels of customer service.

3, 6 and 12 month warranties on all parts

We invest heavily in state-of-the-art equipment to diagnose engine problems quickly and efficiently. If your car is beyond repair, we offer a full supply and fit service on low mileage imported engines, gearboxes and turbos, with a full 3, 6 or 12 month warranty on all parts.

We have access to our sister company Major Motors huge range of vehicle parts, gearbox and engine stock. Having access to this stock means we are more than likely to have access to the part you need (check out Major Motors commitment to stock shown in the photos below). So, rather than waiting weeks for your part to be imported, we can start work straight away. In many cases, you’ll be back on the road in no time at all.



Experts in engine and gearbox reconditioning

As well as sourcing and fitting new parts, our highly skilled mechanics can undertake all engine and gearbox reconditioning work. From re-grinding crankshafts to diagnosing and repairing damage caused by snapped timing belts, we can save you hundreds of pounds on the cost of going to the dealer direct.

With years’ of experience, our professional technicians are equally at home with smaller jobs or complete overhauls. We can even carry out cost effective repairs the main dealers would deem to be uneconomically viable.

To prove we offer the best customer service at our Cardiff based vehicle service garage check out the glowing testimonial we received from our happy customer Dave Bennett pictured below.


We helped Dave fully recondition his Jaguar XKR, read more and follow the link below.
