1970 dodge dart

Sorry but it is not my car and I don't have all the info. on it but just what the owner told me over the phone. I'm just seeing if you guys could give me a quick estimate. Though this weekend I am going to look at it and I will take many pics and get much more info. Also the owner was asking 4800 for it but he said he was flexible with the pice. But If he can't get 4300 for it the car will just set there.
