and why would anyone buy one?

C63 has a two piece one on some. might be for the 19" option in europe.

it's to better aid in aerodynamics as the air that enters the rear wheel wells (and somewhere on the underside) are exited through the vent holes on the tail light lens.
Don't know how much these pieces will affect the aerodynamics through. Even if it did I would never get them as they look stupid and not very integrated with the car.

it is used to make your car faster. i think it adds 5hp depending on where you position it. it also makes you brake faster. so if you add these you can go faster and stop faster, crazy huh?

if you add these you have to add extra chrome trims all over your car, get a toyota supra spoiler, nike/oakley decals, change your car color to primer grey and get gold 14in 1000 spoke rims with white walls.

i wouldn't mind getting the C63 one actually.

I heard it was to reduce spray on the side of the car due to wheel size upgrade.

I have seen them on a lot of SLKs.

These were talked about in another thread where they are standard in some countries as the laws only allow X amount of wheel extension from the wheel well. Instead of a whole new body panel these suffice from what I gather to abide to the law.

I have started a thread in the c63 forum and they mentioned that it may be just a euro spec and not avaliable for the us and australian market...not completely sure tho....https://mbworld.org/forums/c63-amg-w204/257015-quesion-c63-member.html
