Call your dealer, 2 hrs away, and ask her about the offer and what does she recommend and why. If you agree, and want it, make the trip. This equipment is too expensive not to have a relationship with a dealer. And you don't want to risk damage during shipment. Does this offer require you to trade in yours for the upgrade of $500. Have you thought about how will you pack and ship your machine, and risk damage, to get your machine to a dealer who is honoring this offer. Paying for shipping of 2 machines is pricey, but again damage would be my biggest concern
