Those are great highway cars; did many a mile in my Dad's '66 Sport Fury.
I look for a twin to his (light metallic blue, blue interior) from time to time, and the nicer ones have been priced around $16-20K.
This one looks pretty decent, except for the color match and what looks like some blotches in the paint; and the left rear corner may have an issue.
So, yeah, I think it's priced a bit steep, but overall it looks better than most '65-'66 SFs I've seen.
There are 2 other '65s on Feebay at about $37K - oddly, this car didn't show - that's really shootin' for the moon, I think.
