new here - need pricing advice on a 67 Dart Gt

Is that a crack in body filler on the passenger front quarter behind the tire? I would really look for signs of rust under the paint. Get on your back and look inside the rear quarters behind the rear tires. If it's rotted there will be a lot more hidden in other places. Just look for bad body work and go down on price from there. It gets really expensive. I say if it's worth what you are willing to pay.
