Hi,
I agree with Valboo on the Saturn Vue. A colleague's son works at the local Saturn dealership and reports lots of transmission problems with the Vue. He certainly steered me away from them.
As for the Hyundai they do have a better warranty, but when you add up all extra's in the Santa Fe, items that are standard on the SE AWD, like the awesome sunroof, and heated seats ( a must in Canada) I think the X-Trail is better value. I certainly enjoy driving the X-Trail much more than when I test drove the Santa Fe. I think the new Tucson was more comparable to the X-Trail.
The only other consideration would be towing. You can get the Santa Fe with a V6 which I think would be better than the X-Trail's four cylinder.
Anyway, we've had our X-Trail for two weeks and, except for a few of the minor gripes that are well documented in this forum, we really like it.
Good luck with your decision.
Brian
