That VIN looks shady, ive seen some poor jobs, but never that poor. All those pictures and none of the engine bay? The bumper strip looks wavy and isnt secured on the drivers side, if I had to guess id say that it was replaced with something weird(its defiantly not a repop). Being a 77 makes it non smog exempt and less desirable there. I would say thats a solid $3000 car.
There are deals out there on these cars, and they have a ton of capability to be great cars! I love my 74:
My advice would be to wait for a different car, having to smog would be the dealbreaker. Unless you can afford the E-Rod combo that is...
