Should I buy this Cuda?

I have a chance to buy a 70 or 71 Cuda. It was a race car, 440, 4 speed, Dana 604 link I believe. The car has been sitting for a long time, the spark plugs are not in the heads, engine is locked up, body is in rough shape, all windows are in tack and look good, doors are in good shape, lots of rust in trunk and floor pans, he is asking $3,000.00. What do you think. I will try to download pictures.
