A good decal shop can replicate the Crossfire font that is used on the car. They use the logo from The "book" that has all of the "trademarks" and cut the decal to meet your needs (if you can use a vinyl decal).

I used chrome vinyl decals for the two crossfire logos on the "air intake". It looks nice with the letters looking like they are chrome. So does the chrome MB logo I put on the intake.

I have had "original" (factory spec) vinyl decals made for cars, motorcycles and helmets.
