Too bad some missing basics are extra cost options. The MB DVD navation system rates a 1 compare to Lexus which I rate as an 8. I got a great discount for a brand new model. My guess is that with gas prices being as high as they are, this model will be a slow mover. Ride is much firmer than I expected. Again I compare to the Lexus GX470. My wife hates the way it looks from the outside. She loves the interior. These are all first impressions. I'm sure we'll both grow to love this car. BTW, the state of MD registers this "car" as a "truck".
