The Doozie was based on the 1931 Duesenberg Model J, and it featured a removable top, a steamer trunk in the back, and plastic fenders. It was also one of the last cars produced during the Hot Wheels "Redline" era, which saw Mattel include red lines around the edge of every single car's wheels. Later versions of the Doozie, which was mass-produced until 2003, included all-black tires and did not have the "redline" design.
