The new 360 controllers have glossy plastic pieces where the matte parts used to be.
Only the gray piece on the bottom of the old controllers is gloss black and the XBOX button is now chrome. The thumbsticks are black instead of gray Everything else is basically the same. I have about ten controllers and I am comparing same vs. same. When i say compared to new, I am referring to the controller included with my new XBOX slim that i have never once used. I got a refurb'd one from Best Buy and compared it, and it looks much newer, I don't know why this is, maybe a picture will help, but I do know what i'm talking about...and the one i received is NOT the older one with the gray on the bottom.
PS..BMW FTW (assuming the e30 in your username references a BMW)
