spooner's audi and that mobile living room looking thing in minority report. just because thay can both bring your drunken ass home without an actual driver. that being said, i can't leave out MIB's mercedes benz... it comes with its own white driver to avoid getting pulled over. awesome.
and also anderton's lexus in minority report.

While it may not be as aesthetically pleasing as any of the Enterprises, or as famous as the Mellinium Falcon, it is by far the most realistic "warship" from any Scifi show.
Zero point spin radius based on four independant thrusters, 180º by 180º view for the pilot, the list just goes on. Assuming equal weapons/armor, the ship design would allow it to easily beat any other ship its size from any other Scifi show.
The realism makes it my choice.
