Batman Limousine

Sometimes a coach builder or car designer will develop the "ultimate" stretch limo, adding amenities that are somewhat impractical but which make a significant design statement. One such design includes tandem rear axles to support the weight of an operational hot tub.
These extensive limousine conversions have been performed on several luxury marques and fast cars, including: Bentley, BMW, Cadillac, Chrysler, Ford, Holden, Hummer, Infiniti, Jaguar, Lexus, Lincoln, Mercedes-Benz, Rolls-Royce and Volkswagen. In the United States the most popular vehicles for stretch limousines conversion are the Lincoln Town Car, Cadillac DTS, Cadillac Escalade, Chrysler 300C, Hummer H2, Ford Excursion, and the Lincoln Navigator. There are even instances of Corvettes, Ferraris, Mini Coopers and VW Beetles being stretched to accommodate up to 10 passengers.
