Since you don't approve of Rinspeed's Porsches, perhaps you'll appreciate what Rod Emory has created:
I used to talk to the guy when he and his father were at Eola Village, north of Amity, OR; at their Porsche Camp-out swap meets. They ran their Porsche resto shop out of what was at one time an Army Cavalry post.
Jay Leno talks about collecting Lambroghini tractors, but I saw a 3-cylinder diesel Porsche tractor there that sold new in the Salem area in 1957.
The story on the 1960 Panhard PL17 is good too.
