Well, it does have 2 carbs. And 2 antennas.....And about 3 or 4 different car's interiors, too! https://dallas.craigslist.org/dal/cto/d/1964-buick-riviera/6325188350.html
One interior photo shows Pontiac steering wheel and seats with G/P on door panels, this one and another are not even Buick.....
Sometimes people will put a shot of a different car than the one advertised hoping to get inquiries on them. Bob H.
