Well i found a 1993 XJ on Craigslist for a decent price. Its a 4 door 5 speed, red, 225k miles, and the guy said its in good condition. The problem is he was driving and took it out of 5th gear, but it was really stiff. After that it was stuck in neutral and has been parked since. Any ideas what this could be? If the AX-15 needs rebuilt, how much would it cost for either the parts and i DIY it, or have a shop do it?
