Your first question Hawker, has as many answers are there cars. Every used car and it’s seller have a story to tell and you can find good deals at either end

Mechanically, i haven’t heard anyone talk about big $ unexpected repairs. It’s built like a tank.
Electrically, most are single issue except a “few” horror stories involving key, screem, and reprogramming quandaries.

my car has 52K. Replaced secondary air pump 75$, fan blower transistor $40, mechanic bled out & replace brake fluid that failed moisture test 150$. That’s it !

a fellow somewhere outside Atlanta “stole” a car from a used car dealer last Spring for maybe 2K. Put little money in it and he has a GEM. He is here somewhere as a member.
Find someone knowledgeable when you locate one that looks good. What’s your budget?
