Just oil changes and the like while my drivetrain is under warranty, plus anything else that pops up, like the AC issue on my wife's car. I prefer to do all work myself, but within the warranty period I want all maintenance logged, so if something does go wrong, dealers can't claim I neglected the car.
I've had bad experiences at another shop recently. Four attempts to get something fixed, and not the first time, so I'm just checking out alternatives.
