I love it when people bring us their cars after going to one of them "jiffy" type places. They end up being our customers for life. I've seen transmissions run empty until they seize and the engine 5 quarts over full. I've had cars towed to us with half the engine in the trunk. I've seen timing belts put on wrong, bending every valve in the heads. I've even repaired cars that other (same brand!) dealers couldn't. If a dealer can't fix it, no one can. I like these Wally World types, it's job security for me.
As Piewagn says, good experienced tech are getting scarce, it's hard to start out in such a fast paced profession and not many people are signing up to do it. If you think it's bad now, wait about ten years when all of the experience retires and all you have is the wanna-be's trying to figure out your car,
