whats it worth? 1972 340 4 speed duster

Here are the cons...
No buildsheet
No fender tag
Original motor gone
Been wrecked
bad economy

I think $5800.00 is a bit high.Hunt for that buildsheet.Look above the gas tank,on top of the glove box liner,under the headliner,under the seats,hell take off the door panels and look behind them.I do not blame you for starting at $5800.00 you just need that right person.I think $3500.00 would be fair unless you find that buildsheet.Maybe drop it to $4500.00 and see what happens.There is always Ebay...
