Amphicar
The Amphicar had a lot going for it, seeing as it could be driven into the water. After that, it needed to be greased in over a dozen points, one of them requiring the driver to detach his seat. Most of these were sold in the U.S., but these cars aren’t good for much more than their novelty — the front wheels maneuver both on ground and water. “We like to think of it as the fastest car on the water and fastest boat on the road,” said one owner.
