The Kia Soul'ster, a concept vehicle, is another experiment in cross cultural design. The vehicle started life as Kia Soul, a small, tall car due out this spring, but has been turned into a sporty convertible by Kia's Southern California design staff, which sought to endow the vehicle with the very latest in LA style. The Soul'ster is obviously designed to appeal to a young, hip audience with fold-flat seats that can double as a place to sleep, and a canvas top.
