I'm not sure why you keep quoting text from the SAAC Registry. I think we all know it by now.
Mr. Comer writes for a auction magazine with a reasonably large distribution, at least before the economy tanked, and thus his readers
ARE the auction sellers and buyers that you speak of. I can only surmise, but I believe he's just reflecting what the "general market" thinks about ALL our Cobras, CSX's, KMP's, ERA's, SPF's, BDR's, FFR's, etc., etc.
BTW, I'm not trying to be a shill for Mr. Comer, since I've never met him, but here's his Company's website:

He deals in all sorts of cars and I believe he vintage races his '65 or 66 GT350. I can't recall which.
