You can use color range and adjuct the slider to pick the best amount for each color. Save the selections as channel seps.

You best method for this would be Index separations. You can find a good tutorial here t-shirt designs index color separation

You ask your customer for their contact at Ford so you can get an original 'layered' version of this copyrighted design and authorization to reproduce the image rather than steal a reproduction of the image with a scanner.

Ask your lawyer how he thinks you should separate the design.

Yes, yes - I know you probably won't get in any real trouble for printing advertising for a car that isn't even made anymore.
=========

What you have is a complex bitmap image that needs to be reduced to the four colors you want to use. When your customer grabbed the image, they also saved it in a compressed web only format that does index the colors to limit the palette which will help the separations, BUT, the .gif file you got has mode than 256 individual colors, which you need to reduce to 4, but it can be done with halftones of the 4 specific colors.

Scott Fresener also wrote a tutorial on index separations. U.S. Screen Print & Inkjet Technology
