Can anyone help me date this bike and let me know if I paid too much? I just bought a champagne colored Motobecane Grand Touring that has a sticker on the downpost saying Vitus 172. It has Suntour power shifters on the downtube, a Suntour V-GT Luxe Derailleur, a Tourney crank, and Weinmann 610 Vainoueur 999 front and back brakes. I paid $110 today. Thanks.
