IMAGINATION: It has features you've never even dreamed about

Lexus' LS 460 has it all: seats with massage function, a fridge. It even parks itself and it has an eight-speed automatic transmission, a world first. Finally, relief for the deprived owners of the quaint and rudimentary Mercedes S-class, who get along with a mere seven.

Perhaps your tastes run toward science fiction. The LS 460 L — the long-wheelbase model — offers the optional four-zone climate control, which uses an infrared camera to measure backseat passengers' body temperature. A fully optioned LS 460 L would also be equipped with 11 air bags (another record!), 19 surround-sound speakers, a 30-gigabit hard drive (storage for 2,000 music files with room to spare for the navigation data), and five powered sunshades, to tick off just a few of the car's supernumerary excesses.
