Love our Acadia!
We have no complaints after three months with our 2011. In my opinion, they look a bit small from the outside, however it provides all the interior space you could ever need inside! I would recommend the blue tooth option! As for rolling backwards, I figure it has to do with technology and todays fuel economy requirements (plus, its engineered that way). And, mine does not really role backwards except on very steap grades, not to mention, its not a neutral roll, it does have drag. I kinda like the fact that it does not roll forward on idle (level surfaces), I feel that its safer that way.
