Theres a 77 Wagoneer for sale here in town. 401 w/quadratrac, body clean slight rust, not a dent in it. Interior clean. Glass good. New tires. What are these things bringing?? Im taking it for a drive this morning sometime. Oh he's asking $1500 OBO
Don't worry about the sputtering. It could need a tune-up or a carb overhaul- no big deal. Checking out the q-trac can get quite involved but the important things to check are the chain tightness and engagement of the low range (if there is one) and the emergency drive (4-lock). The emergcency drive uses a vacuum shifter so be sure all the vacuum lines are intact. There is loads of info on the SWB forum. Just search under Quadratrac.
$1500 is reasonable for a straight,running FSJ
