I think you'll find that this is closer to mid-1990s, as RSX was introduced for the 1995 model year and the subject bicycle appears to have the steel fork, which was replaced with aluminum for 1997. As noted, while RSX was only 5th in Shimano group hierarchy, it gave away nothing to the higher groups in the critical areas of braking and shifting performance. Assuming their are no issues and given the inclusion of the shoes and SPD-R pedals, the pricing is, IMO, fair value and the only thing that is excessively high about this bicycle is the stem height.
