Ah yes, mining for lithium is so very environmentally friendly.
Problem with 'those skills' is that most of them are moot these days with all the computerized crap in my car. I don't have a carburetor or points, not sure I even have spark plugs or if you even have to set a gap on them. I think there is a starter and an alternator under the hood...not sure where. And I'm quite happy to sit and knit while someone changes my oil...it's worth every dime.
I budget for regular maintenance as opposed to waiting until something goes wrong and then paying more because it's not just ONE thing. I bought a lemon a couple of years ago; physically there wasn't a scratch, dent, tear or worn spot on the whole vehicle. Just needed a new stereo and the A/C recharged...or so I thought. Unfortunately, the previous owner cared more about maintaining the outside...then the inside to the turn of $4500. Stuff was worn out, which in turn wore out other stuff. Two months later I was back in the shop and it was going to cost another $4500. Owner felt so bad about having missed the "real" issue, because he would have advised me to junk it, that he refunded me my previous labor costs.
As for throwing money...I get that. I LOVED my Tahoe, it was a great truck. But it also had 350,000 miles on it and it was time to let it go.
I now have a 2015 Kia Optima . It'll probably cost me around $800 for new tires and it's due for it's 60K service...around $500. So I'll spend $1300 and I won't need tires for another 4 to 5 years and the next big service is 90k...a few years done the road.
