A diamond encrusted Hot Wheels car sits on display at the Mattel offices in New York, February 15, 2008. This one-of-a-kind car, the most expensive in Hot Wheels history, was made to commemorate the production of the 4 billionth Hot Wheels vehicle.
The diamonds on the custom-made jeweled car, valued at $140,000, total more than 2,700 and weigh nearly 23 carats in total weight. The car is cast in 18-karat white gold with the majority of the vehicle detailed with micro pave-set brilliant blue diamonds, mimicking the Hot Wheels Spectraflame blue paint. Under the functional hood, the engine showcases additional micro pave-set white and black diamonds. The Hot Wheels® flame logo found on the underbelly of the car is lined with white and black diamonds. Red rubies are set as the tail lights, while black diamonds and red enamel create the “red line” tires. The custom-made case that houses the jewel-encrusted vehicle also holds 40 individual white diamonds, signifying each year in the legacy of Hot Wheels.
