I've never been a fan of SUVs or the M-class; I always thought it was rather sleepy looking, and a bit too tall.
This one looks like a cross between a Buick Rendezvous and a Toyota Matrix, but with a facelift. I'd rather drive it than an old one, though.
I'm intrigued by the gauge cluster - it looks quite colourful (an advantage, IMO)...anyway, it looks better than most of the generic clusters you see today. I don't know why car manufacturers don't put more effort into the little things like that.
For example, key design...
I can't find a picture of the key from the Carrera GT, but it's even more elegant - a silvery teardrop with no teeth on the key itself, just a wavy line running down the middle, and it fits flush with the ignition as if it's a part of the car.
Then you have the key that Ford includes with its GT - just plain "FORD"-embossed black plastic. Oh well.
Anyway. This new M-class also looks smaller than the old ones - perhaps the track's wider, I dunno - but it looks decent overall.
