I'm thinking of selling my MARINONI which I've had for a while, but hoping some people with more knowledge can tell me what it's worth. I don't know when it was made but it has a 56 cm Columbus frame, 700C Wolber alloy wheels, 7-speed Sachs-Maillard freewheel, 2-speed alloy chainset and Shimano 600 derailleurs and brakes. The blue/green paintwork is almost perfect. What's it worth?
