We saw these images on Motoblog and well, aren't they cool? The three-wheeler in the pics is the Piaggio Ape Calessino and from what little we can understand (Motoblog is an Italian site...), it's a limited-edition model based on a 1950s/1960s machine, which also appeared in some Hollywood movie. More details on the Motoblog site here.
