Hello! I am looking at a 1991 YJ ad and have wanted one for years. It has the 4.0 Liter 6 cylinder engine paired with a 5-speed manual Transmission with has 180k miles on it, exterior is ok with a few(one or two) patches of "bubble rust" (unsure of technical term but that's what I call it), interior if fair with driver seat ripped (if I buy I will replace them). The rear panels have been replaced with textured steel panels. The seller is asking $3k. Ad does not include undercarriage pictures but I plan on asking for some before I set a meet. Is there anything else other than the frame I should look at specifically? Everything else on this car appears to be stock and unmolested.
