A bodies in my area average about 20k for a running project. I'd have a hard time paying $40,000 plus for a 340 duster. The only reason for this is because of the used car market went nuts. I haven't checked in awhile but at one point the banks and the insurance companies wouldn't loan or insure what people were paying for A bodies because the value wasn't there. I still say that once the used car market comes down the value of the classic cars will drop off and people are going to be sick, remember what goes up must come down it's happened before and it will happen again.
