Here's a followup for those who may be interested.
We decided to post it on craigslist for $9500. We got some hits but interest was low after two weeks. However, as everyone knows, it just takes the one right buyer. It sold for $9200.
Thanks to everyone for their comments and suggestions. I incorporated many of them into the final posting.
Congratulations! From the look of the photos and the long list of things your dad had renewed and improved over time, I think that's a fair price for all concerned. I hope you told the new owners about AIRForums so they can join us too!
