Many/most places that work on cars are, IMO, crooks. Many, MANY years ago, I worked at FLAPs and saw many, many instances where shops were trying to screw people over for something that should have been a cheap, easy fix (in one case, it was total fraud for something that I fixed for free by screwing the oil filter on). I've had several shops recommend work to me that was either their fault or completely bogus. I don't think they are all malicious or fraudsters. Many may be crooks due to incompetence.

If/when you find a trustworthy shop (they are out there), hold on to them as they are rare.
