"PORSCHE" from aluminum and polish.
You could do a 1 layer Porsche logo. Guy with a sign cutter did that in frosted vinyl for the wind stop on my Boxster. Don't know if it can do the detail of the STUTTGART in the logo.
The Porsche logo in layers tacked together. The back layer bead blasted to rough it up and colored darker and lighter for the red and black areas, then the rest a second layer polished to make the outline the name the horse, etc. That would be some fancy cutting with the horsey and elk horns. Like the steering wheel logo above.
A Dachshund outline that could be used as a shoe scraper by the door.
Outline of the Carrera.
One of those naked lady silhouettes like on semi mud flaps.
