Cabe mentions that besides house he also kept "the 1973 Pontiac LeMans." The car he uncovers and uses as a chase vehicle when his SUV is rendered undriveable is a 1971 LeMans 2-door sedan. The car that he drives into the water barrels at the gore point was a 1971 LeMans 2-door coupe.
California only has 53 US congressional seats. Only the state assembly has a 78th district (San Diego), and the seat holder would be referred to as "Assemblyman" rather than "Congressman".
After the Pontiac crashes into the water barrels the gear shift is in the parked position not in drive unless Cabe put it in park before he passed out.
