That car is actually a Holden Caprice, long wheel base version of the Commodore/G8. GM imported them as Chevy Caprice's for police departments from 2011-17. Police departments could order 9C1 or 9C3 packages, 9C3 was the detective package with cloth or leather seats instead of plastic rear seat. They came with either the 3.6L V6 or 6.0L V8. The V8 Caprice was the only vehicle to pass all the CHP speed and handling testing. So if you ever find a 9C3 spec Caprice at a police auto auction buy it.
