Unfortunately, claims of fraud are warranted in some cases. But not all auto repair business owners, managers and automotive technicians are the bad guys. There are a lot of honest, hard working, qualified professionals doing their part in the auto repair industry. And let me tell you something, it's not an easy job.
Sometimes it's just a question of finding the right place to bring your car, truck or SUV for repairs and maintenance. References are important. If you have a friend or associate who's had good experiences with a particular repair shop for a long period of time, by all means bring your car there and see for yourself.
If you're trying to locate a reputable shop without a personal reference, check company histories with the Better Business Bureau.
