I too am proud of the vehicle's heritage and engineering background, but Mercedes doesn't brand them, back them, or even acknowledge the connection. Therefore I see no logic for affixing the Benz logo to a Crossfire.
Ditto.
I don't drive a Mercedes, I drive a Chrylser; one of the most unique models they've ever made. I know, and affectionados know it's heritage. That's enough for me.
And even after reading and re-reading the thread, I still can't figure out what your emblems are designed to replace? How about designing a -C-r-o-s-s-f-i-r-e logo that "emerges" when the spoiler deploys?
