I remember hours from my childhood where I would lay faced down on my belly, meticulously plotting on the floor playing with my Hot Wheels car toys. Whether I be staging an imaginary Daytona 500 or a raging demolition derby, it was always fun. In honor of the 40 years Hot Wheels has been providing similar hours of fun to the young, the most expensive Hot Wheels car ever was unveiled at the American Toy Fair in New York. Decked in more than 2,700 diamonds, weighing around 23 carats, and cast in 18-carat gold, the 40th anniversery Hot Wheels car is estimated to cost around £70,000 (around $140,000), this is one of the most expensive toys one can ever dream to own.203327
