I am "re-buying" a 2002 Gary Fisher Marlin from a friend. The bike was my older son's and he sold it to a friend of mine when he outgrew it in 2005. She has ridden it infrequently and is buying a road bike instead. She has offered to sell it to my younger son. It is in good to very good condition. Does anyone have any ideas as to what is a fair price for the bike?
