Have to say though, with what we know now the electrical systems are quite outdated...ammeter bypass anyone?
But yeah it's a shame to see how Chrysler used to make such great cars and now they're just meh, save for the halo cars like challengers etc.
I remember reading somewhere that seatbelts + airbags resulted in about a 5% lower fatality rate versus seatbelts only. Depending on whom you ask, every bit counts, or it's not really worth the added expense and trouble that comes with needing to perform repairs around the airbag systems (don't tilt that airbag sensor...)
When you say beat, what do you actually mean though? If you buy a car for its 0-60 time then you might as well just get a tesla and call it a day. If you buy a car for its cost then you get a corolla, or something that you couldn't care less about beyond oil and air filter changes and you can depend upon to get you from A to B and nothing more. Though I have to say the toyota tax is real, corollas used to be a cheap runabout. If you want something fun, that puts a smile on your face even just
thinking about driving it (and it doesn't have to be a 60s muscle car either), older cars are much more likely to do this, at which point then you go and buy whatever it is, because as time goes on, it's not going to get any cheaper, and before you know it, when you DO have the money that you worked your *** off for, your body is too far gone to actually enjoy it.
As for OP's original question, old cars have everything I want, and none of what I don't need.
I really don't want anything newer than the year 2000, maybe 2005 at most. For me, late 60s had style, late 80s was when EFI was starting to be perfected, and the 90s were the peak of reliability, safety (though to be honest I put that on a back seat as I just drive like everyone around me is drunk and keep my head on a swivel at intersections), tunability and ease of maintenance (most of the time) and emissions components.
