Whats it worth

Well the main thing as you know is to look at the body. If it has very little to know rust, then that is a big savings. The '73 and up Duster's might not be as desireable as the earlier models, but still pretty popular. Look at some of the crap out there for sale. With nothing but rust. Never know til you check it out. Never know what the owner might take. They may need some money.
