I hear you. Any interest in learning though??
I've saved myself a crapload of money over the years by learning to do my own maintenance & repairs. Also means I can comfortably own older cars (which means I've never had car payments). For the rare times I do have a pro mechanic do work, I don't have to take their word for it - they know I know what's going on.
I bought my first car, and the next thing I did was go to the library to got a book on "how engines work".
Gotta start somewhere! Helps to have friends/family who can help, too.
