the 97-98 were some of the worst years for reliability on a wrangler.2007 fj and jk are both first year so thats a draw.I think you find that you will pay more for a fj and it will have more power and might be more reliable but parts will cost more and be a little harder to work on.now a jeep is a jeep,so who cares about the rest.
