Must have missed your first post "180", it's a great idea. But I don't know how anybody could come up with the "List" if it does exist.
Probably everytime someone here on the forum buys something from a Mercedes dealer for their Crossfire, they could go to a "special" place here on the forum and list what it was, its price, and it's part number.
I'll go first:
Mercedes oil filter, part# 000-180-26-09, $20.32.
Mercedes seal ring, part# 007603-014106, $ 0.90.
