Not to get "too political" here but the automotive repair industry has gone to shit and it can almost all boil down to the "Cash for Clunkers" program. It nearly singlehandedly destroyed the industry, taking hundreds of thousands of perfectly good cars off the market forever. Between that and the automotive companies purposefully reverse engineering parts to save money, planned obsolescence, etc. They don't want people to fix their cars anymore. That's the truth of it. They want you to finance a 30,000 dollar pile of crap, drive it for 4 years, then roll your debt over into another 30,000 dollar pile of crap, and making parts and systems that are more expensive to fix than buying a new car, it's all garbage.
Yeah, I could go on and on about this. I went to a top automotive school and paid thousands of dollars for a degree in an industry that collapsed just after I got said degree. I'm just a wee bit salty about it
