As suv_guy said, it's MUCH better looking than a minivan (I don't really like the new Chrysler/Dodge offerings either, they look to low to the ground in the back or something; Honda uglified the back end of the Odyssey w/ it's MCE, the Sienna isn't exactly a looker (no offense to those on here who own one), Kia/Hyundai's are interesting)
The Flex looks great in person. I'd buy one, ESPECIALLY over a minivan.
