Cars, Mattel, miniature cars (McQueen, Mater) Color Change I want to sell them as a set, so individual sales are not possible. There are scratches and stains. Some items have a lot of scratches. Some items have many areas where the color change feature is missing. Color change miniature cars change color when placed in hot or cold water.
