The GT's were decent road bikes. I think the 5.0 was the absolute bottom of the line, with the 1.0 or Team being the best. If its really cheap its probably not too bad of a deal but get it checked out by a shop. GT's are extremely stiff typically, since they are aluminum which is stiff to begin with, and they have that triple triangle rear end. Stiff is good if you are racing, but can be tiring on long rides.
