going to look at another Mopar 1972 Dart
Touch call on price, given the nature of the economy today.
If I found no rust and the car was very mechanically sound, maybe $4500-5000.
He probably believes it's worth a lot more (to him it is --- he spent $$$) but I would be betting that he would have a hard time moving this car for more, in these economic conditions...
Lots of things to consider: quality of the bodywork / paint, the items you mentioned cost $$$ to fix, and the fact that people will not be beating his door down...
Just my thoughts...
