Toyota Camry, Chrysler Town & Country, Honda Odyssey, Saturn Vue, and Honda
Accord. All were purchased used for pretty cheap and went to crap fairly quickly. On each one I've traded in I've crossed my fingers the dealer wouldn't notice all the problems they had (none of them noticed - sucks to be the next buyer).
The Honda Accord I bought was a 2014 with only like 13,000 miles. Thought I'd drive it forever. It hit 90,000 miles and needed a new transmission which with the new tires it also needed was going to cost like $4k to fix. Instead I traded it in (dealer did not notice any transmission issues) and essentially rolled that $4k I would have lost into a new F-150.
And the price of the new trucks is very comparable to used ones right now.
