Whats the going rate for a 780 Bertone? Hard to judge market value because they dont come up that often. I have one that I would say is a 7-8/10 paint is decent and interior isnt to bad but its not a show car. runs and drives great. V6 car. I would sell it for the right price

 

as you noted, its tough to say since so few get sold. You may want to search asking prices on national sites like Autotrader classics or consider posting the car on an auction site like bringatrailer.com. BAT shows a few Bertones that sold in the 8-12K range.
