73 Duster 340 4 speed (not mine)

The following car sold from this site in early December, for a good bit less than the asking price and would be a good comparison.

Notice that the car at the link is a '73 Dart Sport 340 with a pristine unrusted body, a factory air car with an excellent interior with all the factory pieces intact and the overall condition of the car being well above average, if not excellent.
