We all know that our great cars were produced in one of three available colors. Now, if someone is lucky enough to own three Bullitts, he or she could thus have them in any of the following ten color combinations:

All green.

2 green and 1 black.

2 green and 1 blue.

All black.

2 black and 1 green.

2 black and 1 blue.

All blue.

2 blue and 1 green.

2 blue and 1 black.

1 green, 1 black and 1 blue.

NOW...here is the tough part: when figuring that any one of the cars listed above could, or could not, have the Mach stereo option how many combinations - encompassing BOTH color and the Mach stereo option - are now possible, e.g., three green ones all of which have the mach, three green ones with two machs and one non-mach, etc., etc., etc. There is a relatively easy way to figure this question out without having to really do much calculating at all...do you see it?

Good Luck!
