Steve, the differentiation between Spohn and Barris (not familiar with Winfield) is indeed a very slippery slope, splitting hairs if you will. Is it because Spohn was a German coachbuilder, and Barris an American "customizer", but still a coachbuilder of sorts? Each took a chassis and powertrain of possibly earlier vintage, and built a custom body to a client's specifications. Some may argue this 1957 Spohn is not as tasteful as a Barris creation, that is for the beholder to decide. I refer you to the Monkeymobile. And each was built for a different type of client. I'm not sure if being a movie car should have any bearing on the acceptance by AACA. I do understand the mission of AACA and agree we should stay in our lane. But to say this Spohn is different from an authentically restored, or unrestored Barris, is indeed splitting hairs.
I am planning a road trip to the Headquarters to see this creation.
