I just purchased a 2010 Flex SEL. I was pleasantly surprised of the room inside, especially the headroom. I test drove many vehicles in the same price range and determined, for me, that the Flex offered the best value for the money.
The Sync system is great, just takes a bit of getting used to. The USB port allows easy access to music without having to use CDs or the IPOD.
Probably my only comment is like others, a little better fuel economy.
