I believe they are Dodge Chargers. Very popular around here for police use.
Rebadged Holden Commodores, formerly sold as the Pontiac G8, now only available for police and security fleet use, rebadged yet again as a Chevrolet. Excellent cars, rear wheel drive, 5.7 V8. Too bad they didn’t roll it into Buick as a Grand National, or Chevy as an Impala SS.
