Used a large independent to MOT all the Z's and family cars for years, 5 cars in all. New service manager last time the Z4 went in, I did pre MOT check before and all fine, when I went to collect he tells headlight bulb out so replaced it £16 extra on the bill for supply and fit. couldn't argue but know it was ok when it went in, now go to a MOT only garage that doesn't do repairs and get a fair test whilst I wait.
