wanted this for a while...
I actually bought mine from here:
I bought it in person so I'm not sure if this is even the same product but it looks like it.
I did buy it from Boraparts but I picked it up in person (the link was for reference). They have a lot of parts in inventory but don't update their site too well. If you call them with the part number off my pics they should be able to tell you if they have one in stock or not.
It does fit other cars as well but that particular switch shown in the pics came out of my 2004 R32. It is not chrome but rather a stainless finish.
