That one in Tennessee looks like the best one you've looked at so far. Mark has the right idea, road trip. However, heed DieselDog's warning, anyone who would put a hideous mirror like that on a fintail may have botched the head up without knowing it.
A couple months ago after my friend bumper carred his girlfriends 2000 Passat, he was in the market for a car. He saw a '63 fintail on craigslist very much like mine except US spec and auto trans asking $2000. The paint was faded on it but that isn't much considering what Grezmonkey did to his 111. He said it purred and shifted like a dream and offered the guy $1400. Seller said that wasn't out of the question but my friend was still looking and ended up with an '87 325i coupe. He was flabbergasted when I put his entire drumset in the trunk of my fintail and kicked himself for not buying the fintail. Though I think the Beamer fits his temperment better.
Autozen has good advice, California is a buyers market for used cars. No one wants an old car out here, us notwithstanding.
By the way, I should ask the guy I bought the 300E and 280SEL from. He has 11 Benz's, multiple 108's, 111's and 123's. He even had to rent a space to store some of them. I think he has 4 finbody's and may be looking to trim his fleet. Although when I bought the 300E, he said he couldn't hold on to the money and bought a cream puff 123.
He makes me feel better about having 4 cars, a bad influence though.
