Victoria is the only city where we've seen these vehicles en masse. In fact, I don't think we've seen them in any other part of the country. The micro trucks are known as "Kei Trucks" and are imported from Japan. Some brands include Daihatsu Hi-jet, Honda Acty, Mazda Scrum, Mitsubishi Minicab, and Subaru Sambar.
Developed in the 1960s, they are all right-hand drive and feature 660cc water-cooled gasoline engines. Owners will very often go to great lengths to personalize their trucks with elaborate paint schemes.
