That car has long belonged to Phil Jackson, (not of NBA fame). He is(was?) a prominent Mopar muscle car collector with many rare cars including an orange 70 Hemicuda convert. That car(Daytona) is probably one of the best hemi wing cars in terms of provenance and rarity.
I would still like to think a car like that is worth 4-500K in this down market. If there is a mad resurgence in prices for rare musclecars again, expect a car like this to lead the way.
And I am really not much of a fan of wing cars, but I can certainly appreciate the significance of the car.
