Agreed, it does appear to be a hybrid with 700C wheels. Wheeler tends to be one of the brands to which many C&V members thumb their noses but some of them were quite decent and offered good value. The 5xxx series tended to be mid-range, so $100 is probably a good deal but the shipping may erase most, if not all, of the value. The frame appears to be lugged steel and the shift levers appear to be Shimano Rapidfire (as opposed to Rapidfire Plus), so it should be very early 1990s. However, to have a better appreciation of the value we'd need to know the tubeset and components. Additional pictures, particularly of the drivetrain, shifters and brakes, would be a big aid.
