And now for something completely different.
Full disclosure up front. I absolutely cheated with this one. It's one of several cars I've "found" over the years when I attended the Arcane Auto Society's annual meeting in San Francisco. Nice people and a whole lot of weird machinery. This Amphicar was parked in the alley behind the building for a short time at the end of the meet. Public street, weird old car, good enough for me. Where else are you going to see an Amphicar, anyway?
