Thanks all for the great responses. I actually own a purple 53 GMC - link below. But it was completely modernized when I bought it. Not much to do but enjoy it - which I am!

The seller is asking 5k for the 41 Chevy. I am no expert but I did have a friend who is a meachanic look at it and he described the body as rough. The fenders have some rust and one hole. It's lacking skirts, tailgate, windshield. etc. The engine does turn as noted above, but the brakes are locked and the seller is not offering to try starting it. its been sitting 8 years. He suggested boiling out the engine... and I am thinking - how do I do that? My mechanic says offer half, and get a flatbed towtruck to get it out. Then he gave me some good step by step instructions on what to do next to try to see if the engine is good. It does have a title, but no keys.

Thanks again for the great advice, any additional tips at all on what you would ask the seller would be much apreciated! I am likely to make a decision soon. If I buy it, I would consider it a likely 10 year project.

What a great group - Thanks much!
