Paperwork notwithstanding and based only on listing pictures, the OP car looks comparable to the red one also linked in this thread. The latter car is more hot-roddy but it's still flathead powered. OTOH, it's a 5-window trunk vs a supposedly more desirable 3-window rumble seat. Yet it sold for more than four times as much. I know there's plenty of money in Palm Beach but I wouldn't think that alone explains the difference.
