Saw my first S-Class coupe tonight (S550).
Wow - what a grotesque and absolutely hideous vehicle. Mercedes completely screwed up the proportions of the car. From afar it looks like a bigger E-Class coupe.
All in all, it looks like a modern day S500 which I suppose is exactly what it is, but Mercedes really fucked up especially when you look at what a beautiful car the previous CL was. Perhaps my opinion will change when I see AMG model, but I'm not counting on it.
