The Pontiac 2+2 is a full size automobile that was manufactured by Pontiac, built on the B-body chassis. It debuted for the 1964 model year as a trim-only option for the Pontiac Catalina, with special door panels, bucket seats with a center console, and exterior badging. Pontiac marketed the 2+2 as the "big brother" to the popular Pontiac GTO. It continued as a series in Canada until 1970. All Canadian-built 2+2's were equipped with a Pontiac body on a Chevrolet chassis, with the full range of Chevrolet engines available from inline 6-cylinder to big-block V8.
