I see you have your car on Ebay now. You will get a higher bid on BAT, where, I think, potential Buyers seem to have a lot more money than sense.
This one (below) you noted, was bid to $35,850 on BAT. It has been on Ebay ever since at a price of $50k and the highest bid has been $17k, but generally around the $13~$14k. And it does have the correct style chrome bumper for a square tail light car.

The two others you mentioned are round tail light models and they, for whatever reason, are more sought after than square tail light cars.
Your car is fine looking but don't be depressed when it remains unsold on Ebay……...try BAT.
