Anyone know about how much a fair condition GW with 42,000 miles might be worth? It was taken apart to reline the gas tank and then the guy passed away. All the parts are there and it cranks and sounds good. Tires are in great shape. Very little rust. I had a CB-550 back in College but it was stolen and I´d like to get a cheap bike to see if I still have the riding desire. Please pass any advice. The guy is asking $900 and I´ve offered $800. Is it a good deal? Let me know your thoughts!
