I have a vin # , a build date, and a delivery date. So I just followed the link above to confirm. I also get "no matching vehicle. It asks for a 17 digit vin, and I thought mine looked too short but on the real print out from the dealer it lists the vin# but only 7 digits. Is there some special code that goes before or after those seven? Of the seven three are R3X which is High Roof EL T250 single slider.
