Might be worth it
Earthsurfer, with my bumper to bumper discounted second year warranty coming to a close I made the call to pass on buying another 4 years for $1900.00 thru a 3rd party based on input from the posts above. It just makes sense to save that monthly amount playing the odds that I won't have a one time repair on the scale of $1900.00 or more, or even a string that equals that amount over the 4 years of use. But in your case, in my opinion 7 years for $1500.00 sounds like a solid deal, especially with no deduct and since you are buying it at POS you can roll it into your loan (unless you are paying cash of course). If it's rolled in to the loan you would be paying for it as long as you are paying on the unit and it will raise your payoff amount which has to be factored in with the depreciation of a new unit to determine how long it would be before you could get out of the unit and not have negative equity. The trade off is you are paying very little overall for a lot of peace of mind. Only drawback would be that warranty work does typically take longer to get back versus folks paying out of pocket. If the warranty has good coverage and isn't too cumbersome with inspections / maintenance etc. I say it would be very tempting.
