I don't know where to begin, but with such a expensive price tag a C class like nav screen install looks cheap.

And why is AMG Mercedes so stuck on a front engine sports car design? Smiley  Do they not get free calenders at work?

The GT seems like just another expensive "yesterday" car shaped with very little cleverness. Look at the length of the nose versus roof line height and the rear window angle. The ratios are not too pretty. In fact it looks like three different cars on one chassis. Even they have to know its not pretty.
