I've been looking for a place to buy one of these since I got the car. Any sources and general price range - is it a more or less supported install, or is there some messing around?

Well, I think there is at least one other member here that has one. Do a search and see what shows up. Love to see a pic of it. Should work on the C55 as well I would think.(?)

Good luck finding one...

there are several people on this board who have the safety car steering wheel - most of them are to be found in the non AMG section...

We have these steering wheels in stock (new, original mercedes/AMG) and offer them for 650USD shipped.

greetingz,

Harris charged me $850 for my steering wheel.
