I just got a 2011 C300 Sport, with about 10,000 miles. This is my first MB, my last car being a 2002 Audi, 3 litter quatro, which I kept for 10 years!

I'd like a little more horsepower and I'd like to replace the lower plastic grill that has a small hole in it.

Any and all enhancement suggestions of any kind would be appreciated.
