I'm looking at a 1997 4.0 with 90k on it. Going to be driving about an hour to look at it. I never owned a wrangler (always wanted one) and need to know some things to look for. I'm not a mechanic and don't know a whole lot about engines beyond the basics. Can anyone give me some red flags to look for or common problems I should look for. The asking price is $5500.00 which seems reasonable for a 4.0. The pictures show some slight rust on the bumpers but I see that on wranglers a lot here in PA. Also what does a new soft top run on average these days?
