The non-Kaiser affiliated labs here use the Corolla, Focus, Matrix or the Prius here. Heck, the gas, electric and water company use the Prius or the Civic Hybrid. My town dumped their Crown Vics for hybrids.
The county runs a very diverse fleet: CNG Camry, and Accord, Vulcan-powered Tauri, Stratus, Cavalier, Focus, Escape Hybrid, Prius, Civic Hybrid and CNG, all the way up to P71 Crown Vics and F550 diesels.
