Great so far. Ride is smooth, quiet and acceleration in Sport Mode is excellent. I would like to refute a few negative points that I read prior to buying. 1)the backseat- yes it is small and most times a tall driver will have to put his seat up for someone to even sit behind him. However, unless you have a family, realistically how many times do you really have people in the back? If you do have a family there are plenty of other options(ML, GL etc)
2) Fuel Economy- It's not terrible. about 22 highway/15 city for me so far
I laugh when people spend 40,000 on a car and then complain about gas. If you have 40K to spend you shouldn't be sweating gas. if you are, get a Honda CRV or Civic.
Command Nav, Pano Sunroof, Lighting package. Sport mode transmission. Quiet Ride, smooth ride over harsh bumps. Build Quality
I think they are addressing them in 2013. Mainly a Diesel with great fuel econ and a slightly more efficient V6.
