His ad says the car has the "big corvette engine," but wouldn't this be a FWD Cadillac, making it more likely to be the Northstar? He may be right about the damage being cosmetic only, and since it looks like it is limited to the front end, I suppose it could be repaired using the front clip from a standard Cadillac... but I don't see a lot of value in dropping $4500-10,000 on a car that needs its front end rebuilt, especially if the owner is talking out of his bottom quarters as to what the car is and what it has under the hood. (I hope it's not a fellow site member's car.)
