I spoke with a guy in Madison on his way to the HotRod power tour who had a Amphi-car. In talking with him, I found out he bought it from a guy in Illinois who restores them.
That guy is known as “Dave the Wave”.
I was also told he had a Citicar.
I looked him up and found a YouTube video I had seen before. It features Dave the Wave and his Citicar.
