I [attempt to] keep two vehicles maintained, for just myself, on account of one of them always malfunctioning.
One of them is actually fairly reliable (used as work truck); but I'll never buy another Subaru.
I don't recall my 80's cars having any significant issues outside of standard stuff and "has driven more than 250k miles" issues.
I'm pretty sure my 85 Cherokee had idle problems too. That jeep was scary to get on the highway. SO slow.
