Heavy Chevy is right! Although, my brother says it feels lighter to drive than my old Dodge.
It has ONSTAR, Chevy's MyWi (whatever that is - it's on the screen for the radio), a back-up camera (which is friggin' awesome to see in action), it has a Samsung TV which is twice as big as the one in the Dodge, and frankly, bigger than the TV my brother has in our living room! There's even a cooler between the front seats!
The tie-down system is a "smart technology" one ... when my brother comes to a stop, the back tie-downs hooked to my wheelchair ratchet themselves more so as to negate any unnecessary rollage, and then go back to where they were. And, the lift? WOW! It has this thing, where, when it's either deployed but not down, or down, the van cannot be put into gear. The van has this air-ride system (similar to what Range Rovers have) and let me tell you, the ride is ... OMG!!!!!!!!!!!!!!!!!
