The Z-Whiz is a Hot Wheels casting which was first released in 1977, the last year of the 'Redline Era', and is based on the Datsun Z Series S30 body style 1969-1978 Datsun 240Z 1969-1973, Datsun 260Z,. 1974, and the Datsun 280Z 1975-1978. It's name is a play on words with the phrase 'Z Car', referring to the series of cars produced by Datsun with the suffix of 'Z', and the phrase 'Gee Whiz'. The Z-Whiz also has three international releases from Italy, France and Mexico. The Z-Whiz Was the a first in Hot Wheels History; as the First Japanese Import to me made into a casting.
