I missed out on my previous buy and am looking at a 97 Wrangler Sport with auto transmission. I was wondering if there are any common problems to look for. It has 94,000 miles on it and looks like new. Original paint too. I want to put a hitch on it (it never had one) I assume I can get a wire harness plug for that, right? It has a soft top on it and comes with a hard top as well.
