There are really only two bits that benefit from multi-colour/material - the wheels and the fascia.  Both can be printed as it.

The fascia has the digital logo, but if you print it with the digital logo merged in then you could always make a transfer from the logo and put that on instead.

I've included 3mfs and also the original Fusion project.
