The Porsche 911's great grandfather is going up for auction this summer and it could well be the most valuable car ever sold with the Porsche name on it. The Porsche Type 64 looks a little like a child's clay model of a modern Porsche. This was the same basic idea the Porsche car company would use in its first car, the 356, and later in the 911. As the earliest Porsche sports car, and with a direct lineage to today's 911s, it could be worth $20 million to $25 million, according to experts at Hagerty, a company that insures collectible cars. That would make it the most valuable Porsche ever sold.
