I thought it might look more modern to add a "Euro Style" shark fin antenna, even if the design is BMW.

In Hawai'i, besides Safety Check and Inspection you need a Recon Permit (R) as I stated earlier. It is ridiculously lame and since there are so many modified cars in Hawai'i (especially Oah'u), minor upgrades like rims and exhaust need a Recon Permit to be considered legal to drive on the roads. For a long time I never had Recon and I was hassled pretty badly, but I have only been pulled over for Recon in Waikiki. To cops, no recon on a car is an easy target. 
I needed to raise up and reweld my AMG exhaust and while I was at it I also removed my catalytic converter and replaced it with a 2 1/4 inch pipe. It's much loader and throaty. I have heard that the catalytic converters on Mercedes cars are very restrictive. I wouldn't be suprised if it was better to remove my cat since my car is rather old and stuff tends to buildup in the cat.
