You could ask Specialized if it was the entire '02 year or specific serial numbers. Here is their site :

You might want to call them to get a quicker answer so the bike does not sell before you find out. You could also have your LBS call for you and if they are cool they will give you the truth. If you do get it and the frame does give out, Specialized may even replace the frame at no charge but i would want to find out first.
