Are there any 1968 amc red white and blue color amx cars?

While AMC AMX cars from 1968 were offered in a variety of colors, there wasn't a specific factory color combination officially called "Red, White, and Blue." AMC used a much more specific naming system for its colors. It's possible a car was painted this way after the fact, a custom paint job. You might find a car *resembling* that color scheme but not from the factory.
