I have the opportunity to buy a 1972 charger SE and I was wondering what anyone thought it would be worth.  Here are the details:

1972 Charger SE
440 Engine (not original)
-The engine does run, but not great
-new radiator
He says the underbody and frame is in good condition as far as rust goes.
The car was in a head on collision, years ago, in which the hood and front quarter panels were replaced.
-He says there doesn't appear to be any damage or bends in the frame from this accident.
There are a few patches of rust on the body and some signs of bondo, with some rust on rear quarter panels.
I believe he said it was originally a vinyl top but it fell apart, so a hard top was put on.
It has been garage kept for the past 20 years.
The hood has been bent, as if someone tried to close it with something in the engine
Interior looks to be in good condition
Trunk is rusted through
His reason for selling is disinterest.
His asking price is $4600

Could anyone give me an idea of what this car is actually worth? Thanks in advance!
