My original question, which was answered yes, was could one purchase the extended warranty in the future. Based upon several of the posts, I believe this would be the better strategy. I too am likely to purchase the extended warranty, but not at the time of dealer delivery. JFP's time value of money analysis is right on point. However, I did buy a Subaru extended warranty shortly before the manufacturers one ran out. This warranty was provided by Subaru USA and had a $125 deductible and more than paid for itself when I had to replace a fuel pump. As mentioned by others, we are buying insurance here and odds are we should not actually have use it but what if we have too? Parts on today's cars are exceedingly expensive along with dealer shop labor rates. What I would suggest to people is wait a few years before buying an extended warranty but do so only from Honda/Acura directly with a $100 or so deductible. There is some risk that by waiting the rates may go up if the repair experience with the MDX is not good, but on the other hand, if the MDX turns out to be extremely good, the costs could go down. The choice is yours but I know what mine will be.
