“Owned for over 20 years and driven very little.
Mileage 31,402
Runs very well. Very little rust.
I added one leaf spring to all 4 wheels. (The springs can easily be removed.) I put on muffler and dual exhaust. Reupholstered seats. I put 2 new 12-volt batteries in last year. Tires are in pretty good shape.
Look at pictures!
No tire kickers; serious inquiries only.
I listed the condition as “good” only because the vehicle is 66 years old, but I consider the condition as “very good””
