We opted for the extension to 7yr/100K miles.
Thanks guys, we considered a number of different vehicles and I'm not sure if anyone cares, but:
Honda Pilot - didn't care for current body style, so was looking at the previous style. Ride quality was nearly dead last. It was very spacious though and the price was very competitive
Hyundai Veracruz - seemed to be expensive for what you got. Drive was nice, just didn't have the fit and finish of the others. Salesperson was annoying
Volvo XC90 - loved the look and drive and in the end we decided against it due to unknown cost of ownership and reliability and it was a tad smaller than what we were comfortable with.
Mazda CX9 - dead last
Buick Enclave - Liked it a lot, but seemed overpriced and didn't know if I wanted to own an American car
Acura MDX - Probably second choice. Ride was very nice and very well appointed, just a tad outside our price range. I didn't like that only half of the second row would allow entry into the third row.
Chevy Traverse - meh
Subaru Tribeca - really wanted to own another Subaru, but just too small when compared with the Pilot and others.
