What is a ZAMAC car?

A ZAMAC car is basically an unpainted car. ZAMAC is the material that Hot Wheels are casted from.

The term ZAMAC car was first used in 1998. There were 25 carded versions available at the '98 convention along with a baggy Zamac and a 4 ZAMAC car set. Kay-Bee Toys also had some 2 car sets (Same casting, one painted, one unpainted or 'ZAMAC'). In 2004, Mattel released some of the First Editions in ZAMAC. These were a Toys 'R Us Exclusive but were later found at Target stores as well.
