I am with you on this one. You do what you want,like and makes you happy with your car. IT IS YOUR CAR!!!!
On the other hand, be prepare to pay the price for your decision(s), in a positive or negative way.
There are so many after market companies out there that are making nice profits improving and individualizing MB stock cars i.e. renntech, fab design, and lets not forget AMG (now part of Mercedes).
Different strokes for different folks...
