Try this with my characature Mustang. The Mustang you are using has the Ford "Running Horse" that is trademarked by Ford. Would like to see the CHIP'S and PonyCars.com filled with yellow as in your other design.
I didn't put any emblem on the grill of the mustang because I couldn't clearly see what you did with your caricature car, the file you uploaded was to small for any detail to be seen clearly, and in the plate I just used V6. Hoping this looks better than my first entry.
