My name is anthony and i just bought a 2008 c350 it has the multi media package. i need advice on what i want to do just if you guys could help me out by posting links so i could read.

LIGHTS:I'm not sure how i know if it has hids or not but i do want to change the color of the lights to bright white also change out all the interior lights and outer lights to the bright white leds and get clear side markers.

WHEELS: I'm not sure if i want to stick with upgraded factory amg wheels or buy aftermarket wheels. i just want that clean look i want to buy springs also but i don't want to rub at all i know a lot of people here are running 19's but i just wanna do 18's. what are you guys opinion?

PERFORMANCE: i was thinking about a dual intake, eibach sway bars, renntech tune,eisenmann exhaust.

AERO: i want to know where is a good place to buy a good front lip, rear diffuser, and a roof spoiler all CF.
