I haven't gotten the card (I only have 12K miles on it) - but if I do get a card when the 3 years are up - depending on the price, I'd buy it in a heart-beat! If it is offered by DC and costs about the same as most dealers sell their third-party extended warranties - it is usually a great deal for that peace of mind.

I used to think extended warranties were like rustproofing or pinstripes - overpriced and unnecessary - but I bought one for a used 96 neon that saved me thousands of dollars in repairs. Since these motors are MB and never cheap to work on, it is probably a great opportunity, if it truly is an extended warranty. What I mean by that is - it should cover everything the original warranty covered.
