Looking around my market $150 seems to be the going price for any scrap of metal with two wheels. Ive found bikes literally selling for what they bought them for 30 years ago. In fact a large sector of the market puts bikes 150+ without even knowing the brand name much less a model. They just know its a "road bike" premium. Something with the above standards really ups the difficulty, especially if they know it. But if you look long enough you find jems.
