The Reliant Rialto is a 3-wheeled freak from the United Kingdom that featured a 850 cc water cooled inline-4 and the stability of a meth addict who just won the lottery. Apparently the combination of fiberglass body and galvanized chassis has made them somewhat immune to the rust that would normally consume such a 25 year old British lightweight -- and they make a great boat.
The seller of this car has left the basic Reliant powertrain intact, but added a 550 jet ski engine in the back for motive power when in the water. No word on how the spinning bits of the automobile drivetrain are sealed for use on a lake/stream/ocean, but the seller does say it runs, drives, and floats, on or off water.
The video shows the little amphibious vehicle in a previous incarnation (with an outboard motor), but the new version should be just as awesome.
