Vespa's South African division had this stretch scooter made as a promotional gimmick. They refer to it as a family-sized vehicle:
According to Vespa, here's a list of uses for the stretched scooter: it's a sensible family car on two wheels and kids will look forward to going to school on it. You can be the designated driver and still park outside the front door of the party. When you make new buddies, you can take them home with you - and you save money on fuel.
It's a custom job, so don't rush down to a dealership expecting to find one.
