2008 Expy EL Limited - Power Fold Mirrors, A/C seats...far as I can tell, the Flex is missing those only, but it gains those listed below

Flex - Sync, Navigation/DVD radio, the trans downshifts to maintain speed going down hills, HID lowbeams with halogen high beams, power folding 3rd row seat (Expy had also), power folding 2nd row seat


There is more, but those are the biggies. I had put a aftermarket radio and DVD setup into my Expy, but it was never as nice/seamless as the OEM Sync setup works.
