Guys, I bought another 80, with 151 K, no lockers. Owner claims it needs an new engine. His mech at carmax told him so. I took it out for a drive, only thing I noticed out of place was 5 or so knocks upon start up (loud), then it stops and drives normal. All fluids were a bit low, but looked go. No unusual smoke coming from the back, and no overheating. I would like some options and opinions. Thanks guys, hopefully I'll make the next trail ride. Later
