What customers say

Took my Golf GTI for a DSG gearbox service and was greeted by a helpful receptionist who answered a few questions. Staff were very polite. Very happy with the work done. 👍
Tom Griffiths VW
Second time back now to JFA automotive Kent 1st time for an engine & gearbox map absolutely changed the car it is now amazing! Second time was for a dyno on the drag car, friendly staff good equipment free coffee what more do you want definitely recommend
Harry Yates
