Depending on if your character "has class" or not, the MB works....Audi also has the A8L, which is a mobile land yacht, very quick, very pricy....If you want elite, there is the RS6....
I'm thinking if you want a Playboy image, go with a Porsche 911 GT2?....if he is REALLY loaded and wants to stick out....try the Porche Carerra...
