When not sitting at the captain’s chair of his 413-foot yacht, Octopus, Allen can be found cruising the autobahn in his 1988 Porsche 959 Coupe. Originally, Allen planned to drive his Porsche on American soil, but stringent emissions standards and crash-test ratings kept his and Bill Gates’ 959s impounded in customs. Frustrated, Allen gave up and decided to ship his 959 back to Europe, where he enjoys driving it today. When he is in Seattle, Allen has a 1988 Mazda B-Series Pickup that he uses to get around.
