I think the Flex is quite attractive and appealing as a family hauler. It's distinctive, even tasteful (the grille suits it, as does the white roof), and the boxy shape is a blessing for interior airyness and functionality. It's powerful, choice of FWD or AWD, and like some of the features such as the fridge. Don't know that I'd pay the $50 grand for it, but in lessor trims or discounted I'd be taking a very close look. At $50,000 it's a lot of vehicle, although at that point the R-Class at $12,000 more seems within reach and more impressive to onlookers... but we should know by now few will sell at MSRP.
Feel it's a very smart concept for North American drivers.
