Jeremy Clarkson suggests buying a Vespa:
I also liked the idea of a Vespa because most bikes are Japanese. This means they are extremely reliable so you cannot avoid a fatal crash by simply breaking down. This is entirely possible on a Vespa because it is made in Italy.
Via Jeff the Baptist, who quips "Perhaps this explain the popularity of Harley-Davidson's as well?" Heh, probably. Although Harley has improved it's quality control over recent years. Or so I've heard. A company can only count on brand loyalty for so long.
Personally, I've long dreamed of getting a Vespa and riding it from Barrow, Alaska to Tierra del Fuego, and then writing a book about the experience. That's one motorcycle adventure that I don't think has been yet tackled on a scooter.
