hey guys i never post here because i don't own a benz, but i'm looking to buy a c230 kompressor sedan, and am wondering what are the differences between the 04 and 05, and do the 05's come with the more blue looking headlights, such as the xenons or hid's, are there good looking body kits for them, what typical problems do they have and how good of cars are they in general for the money. any help would be greatly appreciated
