Maybe it is http://www.imcdb.org/vehicle_819542-Buick-1929.html where the year was not correctly identified?

Hello,

My grandfather currently owns a 1931 Buck Sedan that he purchased over 20 years ago. He had always told me that this car was used in the 1984 movie The Cotton Club as the "machine gun" car, and I believe that is one of the reasons he bought it. Supposedly it was the car used during a drive by in the movie. If he is correct, believe it could be this unidentified car in the link below. I would like to learn how to go about finding out of this is true? If anyone could help, that would be greatly appreciated.
