"Yes, it is two years older than advertised. I would want something back for that.
Otherwise, there is essentially no difference between a 2000 or a 98 model - but that really isn't the point.
If the "dealer" you bought it from values their reputation, they should be willing to work something out. However, something as simple as confirming the year should be child's play for anyone in the industry - unless they were intentionally trying to deceive the buyer.
If this was bought in a private sale, from "some guys" garage, you can expect that the information may not be entirely correct which is usually why a privately sold motor will bring somewhat less money than one from a dealer (they are supposed to take away some of the uncertainty).
A good lesson here - if anyone is ever buying something "sight unseen", at the very least, request a serial/model number to independantly confirm what is being advertised..."
