First launched in 1968 under the Mattel brand, Hot Wheels started their 1:64 collection of die cast cars with only 16 models. Mostly American muscle cars, there was a Vdub in there for good measure. Designed to scale, the Hot Wheels fad was a hit from the very beginning, and it's only grown since '68.
