So when I got my ET in the spring the dealer sent in the warranty card. I know the warranty transfers with the unit at that point if I sell it within the warranty time. But what if I buy it and keep the card(if the dealer doesn't send it in for me) and don't send it in. I put it up for sell and state: I haven't sent the card in so you can when you get it. So I can keep it for a year, sell it and then send the card in to start the warranty? I see this all the time. How does ML know when it is actually sold from the dealer as that is when the warranty should really start. Do you the dealer report the sale with serial number to ML when sold?
