I'll be the first to say that I suck at automotive diagnostics. I never took auto shop in high school because I was too busy rebelling, and it took me a long time to pull my head outta my ***. But I'm learning now.
I think I fall somewhere in the middle here. I'm newish to owning older cars, but I sort of enjoy working on them MORE than driving them. Eh, maybe 50/50. But the driving force behind wanting to own a car older than me was to learn the fundamentals and actually have something I can work on without pluggin it into a computer. Since then I've been hooked (and broke, LOL).
*That being said* Just know that not all of the folks here who come for advice are going to look a gift horse in the mouth. What I mean is, I think there are lots of us who find the wisdom in this forum invaluable, and are very grateful for it.
I read the same posts from people asking for advice who end up either completely ignoring it, or dismissing the advice that's offered, and I just shake my head. Like dude, you have no idea how much time and money these folks can be saving you right now.....not to mention the free education.
