I see a few interior things that aren't perfect, and the cowl/door jamb area might indicate color change, but overall it looks good.
Of course, photos vs in-person could be vastly different.
Plus, it's a 500 and power windows are pretty rare on early Bs.
(If they're like the ones on a '65 Bel II I had, the work like guillotines !)
A '64 Polara nowhere near that nice just sold on Hemmings for $14,500.
Seems to me a very nice early B 2-door is easily a $20-25,000 car now.
