For the Hawaii vacation we rented a convertible jeep that can be driven 4x4 or 4x2 and it worked perfect for us because we went to the Mountains, to see the Jungle and we drove in the sand so we could change easily the different types of four-wheel-drive systems and 4x4 system was very useful.
Most popular cars rented for the exotic holidays are convertible Corvette and Chevrolet Camaro or Mustang. In Hawaii most cars are american made and there are very few German made vehicles.
