Really a smooth, quite ride with good acceleration. Great turning radius - much better than the S60 Volvo awd. Also responds better to the road the the Volvo or the Jag x type. Controls are confusing, setting the dials requires a look at the manual each time. Like the visability from the drivers seat - judging the front end is easier with the mercedes emblem out front. Very few blind spots. AWD responds real well in the snow - stabilizes quite well.
Visability, stability, overall appearance inside and out - graduated heated seats are nice, seats are comfortable, cut outs for knees in the back seat.
Make pre-sets more user friendly, loose some of the telephone related dash board presets - and better gas mileage would be nice.
