First off, I think that Mercedes has really been doing a great job with design. Especially in regards to the interiors of their cars, Mercedes is doing fantastic.
1. SLS AMG: I truly believe that this is the most beautiful car on sale today. The roadster is gorgeous, and the coupe has tons of presence. Still has a gorgeous interior despite the SLK's rip off.
2. CLS: Completely eye arresting. Finally got to see it in person at NYIAS, and was incredibly impressed. Lovely interior as well.
3. SLK (tie): Although its design is somewhat disjointed, it still is really handsome. Beautiful interior, though unoriginal.
3. ML: Really really pleased with the new ML. Awesome interior, and great AMG sport pack.
4. C Sedan: MB does facelifts really well; and the C is no exception. Great new interior.
5. C Coupe: Lovely, but I still wince sometimes when I see the window kink, and I don't think it's very elegant at all.
