My 1996 Toyota Tacoma pickup truck is still going, with around 400,000km on it, and just regular maintenance, except for the time someone stole the catalytic converter and I had to have it replaced.
DeLoreans didn't even have short-term reliability.
So I've heard... the DeLorean came to mind, because AFAIK, it's the only mass-produced car ever(?) to have a stainless steel chassis, theoretically making it thus immune to corrosion.
Correction: "[...]and stood out for its gull-wing doors and brushed stainless-steel outer body panels, as well as an innovative fiberglass body structure with a steel backbone chassis."
