Did you get the coupe, sedan, or convertible?
I have a 2004 ZHP convertible in black on black. I personally think it looks awesome. The color isn't everyone's cup of tea; I know a lot of people who like some contrast to their interior. Although the color is all the same, the interior textures are quite varied, so the effect is really nice, IMHO.
I have been very impressed with my ZHP. I bought it to replace my MBZ SL560, which is going on 16 years old. I needed a car with a rear seat, and I've always loved the E46 body style in convertible. Hopefully this car will be running as well in 16 years as the SL560 runs now (they wouldn't give me enough on trade-in, so I kept it). Say what you will about MBZ--at least they knew how to build a hell of a good car in 1988.
