Really? You wouldn't want a rail-gun welded to the roof?
Or a 37" LCD screen that drops down from the headliner, with a PS3 tucked away in the jack cubby?
Or remove the rear seat, build a raised, clear plexiglass floor that covers the rear cargo area and fill it with scorpions?
Or build a circular conveyor belt going around the rear compartment and have one of those sushi restaurant setups?
Or remove the front and rear circular driving lights/red reflector lenses and install extendable javelins that pop out and puncture the bumpers of cars that park too close?
Or paint large grommet-holes up the hood and roofline, then paint large shoelaces going across and through all of them, with maybe a large Nike "swoosh" on both doors?
Or...okay, just heated seats and windows that work?
