Well, I've decided I need a Wrangler and wondered if there are any specific things I should consider with the YJ's. Mainly, do earlier models ('87-'90) have more problems and how much should mileage figure into my decision. The ones I'm considering have between 70K and 155K. I don't want to have to rebuild it right after I buy it. BTW I previously owned a 2001 Cherokee. Never had any problems. Thanks!
