Re: 1979 Wagoneer??
Look for the usual stuff . . . oil leaks (rear main seal especially), check for blow by on the #7 and 8 cylinders especially. Look for a lever almost under the driver's seat by the transmission hump, If it is there it has a low range t-case (may not, but it is great if it does). Since it is an auto it should be a Quadratrac (BW 1339) full time 4wd. Look in the glove box. There should be a round switch that activates the 'emergency drive' for the Quadratrac, see if that works (on loose road surface only). Tranny is an AMC cased TH-400, good tranny. For $2k, the interior should be in pretty good shape and the paint decent. Look for rust/frame rot in between the gas tank and frame (the skidplate traps mud and junk up in there, very bad ju-ju). Typically the rear quarters behind the wheels are rotting either on the inside or all the way through, so check for bondo in that area. I hope that helps.
