The Extra-Terrestrial Vehicle, by Mike Vetter and The Car Factory
See that? That's the "Extra-Terrestrial Vehicle" from Mike Vetter and The Car Factory. Mike and his team will build one just for you--and all you have to do is provide a Chevrolet Aveo or a Porsche Boxter for the bones. (Tough decision. We had to break out the 20-sided die.) The company's website doesn't list conversion prices, but it probably costs several thousand dollars, plus half your charisma points and every shot you've got at dating a non-Trekkie. In other words: totally worth it.
