> are you sure this is something you want to get into?
If I didn't rely on my car, it'd be a curiosity, and lower priority than a bunch of other stuff I want to learn, but since I expect it to work when I need it, not understanding isn't really acceptable for me.
If you rely on your car and you're not naturally mechanically inclined, all the more reason to get someone who knows what they're doing to look at it.
