I try to do all of work my vehicles ever need myself because I hate taking it in to dealers. They always seems to come back with other problems than what they went in for. But it really ticks me off when a tech just wants to drive (play) with your vehicle for things like a radio issue. You can request your vehicle not to be test driven, but when they do it anyway or say we always have to test drive our work. What can you really do other than change dealers? Most seem to do the same anyway. Just wondered if others have been in a situation like this and what you've done?
