What customers say

Excellent job by the lads at jf automotive, had engine tune/ gearbox service and tune on my x5, would highly recommend and would definitely use them again!

Took my car in for a DSG service as they were able to get me booked in within short notice. Staff are very helpful and very happy with the overall experience. Would recommend!
J W Davies
Arrived 8.30 Saturday morning, a technician armed with laptop tuned the gearbox,so now the truck changes earlier keeping the revs lower,I was a bit hesitate about having it done,but it's definitely better with no problems.
