I kinda hate to throw a monkey wrench in here, but...I recall that we recently had a very similar '63 150C in the club classifieds, that seemed much more desirable to me than this one, for about the same money.
It had terrific paint, and factory long range tanks, and was located in Iowa. It appeared to be an above average straight tail at a good price. Lori and I actually talked about the possibility of buying it to convert to a taildragger, but since we already have two airplanes that we don't fly enough, we came to our senses, and passed.
The ad appears to have expired, so I don't know the current status, but I'll look it up later today and post the ad here if it's still available so you can look into it.
