Chevrolet is non-existent in the North American Police market, yes, that's a reference to how diminished their presence is now. The Caprice/Impala is gone shortly and the PPV Tahoe has a very small footprint across US and Canuckistan. It's big in Texas because its built in Arlington and they give deep discounts to Texas residents and Agencies. Chevrolet also couldn't unload the Caprices so they almost gave them away and Municipalities with budget issues bought them
Dodge Charger Pursuit is gaining ground on Fords PI Sedan because they have really done good job on their Charger Pursuit.
That agency you mentioned that's using Caprices for K9......that is brutal, that's not good for the dog or the handler.
