People who know these tractors aren't going to bid. So this guy is attempting to sell the tractor to someone who doesn't know Yanmars. Perhaps he bought it in the same way, or bought it at auction with some vague misreprentation (which he failed to note). The seller has slowly changed his listing over time from Made by Deere, to made by Yanmar; from 4 cylinder to 3 cylinder; but maintains the 2002 yr charade.
Maybe he bought the tractor with a 2002 yr representation and continues to believe it.
If someone buys it, maybe they will find out, maybe not. Ebay certainly doesn't get involved or help.
Anybody who buys a tractor from a seller with a total of 1 for a feedback without checking it out is a fool, but there are a lot of fools out there. Waive a "deal" in front of people and many will ignore the facts.
