2001 Nissan Pathinder mechanic's special, fixer, for parts,

This truck starts and will drive but overheats. Replaced both thermostats, ater pump, nd radiator. Than it was diagnosed by mechanic as problem with head gasket/exhaust fumes in cooling .I am no longer trying to fix it. About 6 months on all 4 tires with low mileage on them. Transmission works fine. No check engine lights on. Next emission test in 2017. Got hitch set up, sed for bicycle rack. 4by4 works fine. Some rust. I am a second owner.( parents were first). Local pick up only, referred with tow truck as overheats quickly.
