I would highly recommend Express Gearbox.
I had a nightmare with a car I purchased from a dealership, its an automatic and the reverse gear stopped working as well as displaying malfunction error on dash everytime it was put in reverse as well as the car jolting forward when put in reverse.
As I was getting no support from where the car was purchased I had to find a reputable garage to diagnose the issue, I was told by a number of people and even garages, that James @Express Gearbox would be the one to talk to.
Im so greatful I took their advice.
James was prompt in booking the car and running diagnostics, he explained everything from start to finish. He advised me on what was the fault with the gearbox and how this could be rectified, even though further issues were found, James explained this to me and kept contact throughout. The car now runs without fault, might I add even better than it did when it was purchased. Thanks again, will definately recommend you to others.

Definately one of the best chauffer companies around, used them to start off our holiday, the driver was exceptionally polite and smart, the vechile we travelled in exceeded our expectations, journey was comfortable and pleasant.
In addition to this the driver helped with our luggage and engaged in conversation unlike many others that are around.
Definately will use this company again, highly recommended 5**
