Hey there,
I'm going to get the spoiler from a place in my hometown called Speed Tech, he did the body kit as well. The Touring style spoiler is like this one that is pictured in this link below, except the one I'm getting will be all fiberglass and painted to match the car (no aluminum). Also, the two mounting supports will be closer together. It is shown on the white 190E racecar, not the silver C-class.
