I, too, nominate Paul.

As for von Goertz, the 503 was the predecessor to the E9 (2800 CS and 3.0 CS). That was one beautiful car. My Father bought a 1970 2800 CSA and I liked it so much that two years later I bought a 3.0CS. Which I kept for 29 years. In perfect condition (for a driver).

As for the 507, I've told this sad story before. In 1974 the mechanics who ran Porsche-BMW Specialists, Inc. in Santa Monica (I was their lawyer) got a line on a 507 barn find. If I acted quickly enough I could snatch it up for $5,000. I wanted to do so but my girl friend wanted a new horse.

I was told that the 507 was bought by John M. Stiegler (owner of Auto Stiegler in Encino, CA), who got it running and then sold it for a big profit. I lost track of the car well before the damn horse died.
