Perhaps a road trip showing the car at the National CTCI Thunderbird convention in Knoxville Tenn , Aug 15th - 18th could get you the sale you are looking for ?
Lots of T Bird buyers , sellers and affectionados at those events.
Or - also list it in the CTCI publication of "The Early Bird" for some specialised T Bird exposure.
I"ve always had good luck with a listing in Hemmings.
The side chrome looks cool. I guess the porthole windows are a matter of personal taste. I hear that when you go with the wire wheels on 55 and 56 the skits have to come off.
'57 and later T-Birds too, and it depends on the wheel offset and size of the center spinner.
Unwanted side-to-side movement of the rear axle can figure in there too. There is very little clearance.
If you're looking at the red '55 back in comment #2 those are the optional wire style wheel covers, not wire wheels. And they fit fine under the fender skirts.
This is an absolutely beautiful BIRD, but the one thing that spoils it for me (other than I cannot afford it) is the modification(s) done to the top with the quarter/opera glass. It just ruins the whole car (to me) and the first thing a buyer will think is how much a replacement top is going to cost.
