Cars that needed a tune-up every 10,000 miles along with brakes about the same interval. Plus needing to lube it frequently as well!
While the new stuff is vastly more complex and difficult to understand at the detailed level, they're actually quite serviceable if you'll invest in some manuals and spend a little time studying. You can still learn the gozinta-gozouta system functionality of the engine computer, for example, and do some troubleshooting without having an engineering degree or 40,000 dollars worth of test equipment. A code scanner and manuals can be had for 200 bucks.
I have three kids driving plus a truck for pulling my boat, so I'm up to 6 cars at my house that I service. I can't be an expert on every car, but I can learn a few fairly well. To make things a bit easier, I got my kids all GM W bodies that have lots in common - IOW, learn one, learn 'em all.
IMO, code scanners and the plethora of tech info available both on the web and cheap on eBay (ie, cheap used paper manuals and cheap DVD manuals) have brought the shade tree back to guys like me who thought the same as you a few years ago. But now, I routinely am working on my kids' old cars. We're gonna hit 200,000 miles on one pretty soon
