Another pic of:

Built in the late 1970s by the Carrozzeria Grazia on a stretched Fiat 241 base by Franchin, the Zig-Zag was not just a promotional vehicle. The flashy body shop faithfully reproduces a giant scale spray can. The concave windscreen simulates the bottom of the bottle while a large red button on the rear simulates the spray valve. Inside, there is a real mobile office equipped with a sofa, a contract table and a showcase for products, making it ideal for meetings with customers around Italy.
