Our family run local business has access to dealer level expertise and diagnostic equipment to ensure your car only gets the best dealer-level service at affordable prices. We can save you money! Here is a great example.

Photographed below we have a Nissan vehicle that had a braking problem and the owner went to the main dealer to sort out the problem, the owner was quoted a price of £2500 to order the ABS pump which included the fitting of the part. With this being a high price the owner of the Nissan vehicle came to us and we were able to diagnose the problem, order in the part and fit the part all for £1000, we saved the vehicle owner £1500.
