I have an old Peugeot 12-speed in excellent condition (needs new tires), and would like to sell it. However, I have no idea what it's approximate worth is. It's probably early 80's vintage; the paint job is red, with blue lettering. I didn't notice a model number, probably because I don't know where to look. The bike has always been kept inside, has no rust or rot, and was never really ridden all that much. In fact, not at all in the past 10 years or so. If anyone could at least give me a realistic range, I'd sure appreciate it.
