Normally I wouldn’t jump into a classified like this, but what exactly does this statement mean? The car isn’t a classic and it seems to be stock. It’s a mass produced subaru that a quick search on autotrader turns up several 1999 RS’s within 300 miles of zip 14221, so it doesn’t seem very rare even. So KBB should represent a true value of this car, and the price you could go get one from a dealer for.
