Purchasing a car from a private seller. Nightmare.

Thanks for everyone's feedback. I didn't mention that i took the car to my mechanic and another recommended by a reputable custom car restoration garage in my town. Both mechanics said it doesn't look repairable or if it was it would be expensive. The final word will come on 08/25 when i take it to the custom car garage i mentioned. They would have the frame equipment that would be needed to make the repair and would tell me how much it would cost. again, it doesn't look good. I'm calling the seller back shortly and i'm going to see about returning the car.
