Hot Wheels color changers were made by Mattel from 1988 through 1990 & we’re also known as color racers. The cars made for this series were new colors & Alternate tampos of old castings. This one is the VW Volkswagen known as Baja Bug. It changes from a dark mustard yellow color to a peach or tangerine orange color. The color of the car is dependent on temperature. in each photo on this listing the different color cars are the same car. One color is achieved by placing the car in the freezer. The other color is achieved by dunking it in hot water. Only one car is available on this listing. It is the one in the photos & has been tested for the color change feature. As you can see from the photos it does work although it may not be as fast or as strong as it was when the item was new in the 1980s or 90s. This is typical of the aging process for the color change series. Some of the cars do not work at all anymore & just remain one color no matter what temperature. It’s lucky that this one still has some function left in it. The car is in near-mint condition & comes from an adult collector who never played with the item. Flaws are few & minimal. Other cars from the series will be posted separately so check the shop & feel free to combine your shipping! Hot Wheels Color Changers Baja Bug Vw Volkswagen Mattel 1989
