Thanks for all the replies.
klmken: Good idea on the weather check thing.
Nort: I did do a bill of sales indicating "as is" condition. And you're right, I guess I did let emotions rule a bit, but hey, now I have a Cigarette (not a Formula though!)! I have no complaints about what I got. And I don't think gen 1 vs gen 2 makes much difference. I just mentioned it as a little background info that what I got wasn't quite as it was represented to me but I didn't go after him for it.
Sydwayz: What is pink stuff? Remember, the only ice we see around here comes in bags and goes in to cooler for the foo foo drinks!
Others: thanks for the info. I thought the same thing about freezing block...it would have to sit in freezing weather for a few days to do damage.
I also want to make clear that he hasn't asked me for any $ (yet) and he may not. I just wanted opinions because if I feel that if I'm at fault I would made good on it whether he asked or not. Either way, I feel like crap about it. I always like to do win - win deals. I've bought and sold a lot of hot rods and Harleys and always make sure the buyer is happy. I quite often do follow up calls just to make sure. I've never had a deal go bad.
I guess I'll just wait until I get back from Denver and give him a call to see what he thinks.
