Hi Jim,
From your photos and your description, it sure looks like you have probably one of the best restored Cessna 152 in the world. You should not hesitate to offer it for sale for over $100K +. I would not be surprised if there is someone out there now who has the monetary resources to buy it quickly once you officially list it. Most likely, it will be someone overseas.
I know how attached we can get to our planes. I bought my 1983 152 in 2004 from Harrisburg, Pennsylvania. It now only has 1950 hours TTAF and 500 SMOH. I even had it christened by a priest and named it "LingBird" after my Chinese name. Actually, my son who was 13 years old then, found it on the Trade a Plane site and we went up and bought it over one weekend.
It would be very hard for me to make the decision to sell it when I am too old to fly. I believe we are only stewards of our planes . Surely I would only sell to someone who I feel will take care of the plane. Luckily, my son will most likely take it over one day.
I know that is is a tough decision for you to sell. However, I believe from what you stated, you are selling for the right reason.
