In 2008, Mattel wanted to prove just how big the Hot Wheels brand had become. So, they commissioned celebrity jeweler Jason Arasheben of Jason of Beverly Hills to create a one-of-a-kind Hot Wheels car to help them celebrate their 40th anniversary. It featured 2,702 multicolored diamonds, took more than 600 hours to produce, and was auctioned off for $140,000. Quite the status symbol, eh?
