This is seriously true. I recently purchased a 2002 CVPI that came from the LAPD. It went into auction in April 2015 with 115k miles on it. It was a slicktop (no holes in roof), was possibly involved in a pursuit as a lead unit vs a Caddy Escalade. They used the "grandma" style hubcaps on it that came on the older (98-02) models. I've since swapped them to center caps. But doing the math, that Crown Vic being a 2002 was in service for quite some time. Even if we say it sat in lot prior to auction for a year or two, we're still looking at 10 years of service off of a P71. But agencies are holding onto their vehicles longer and longer it seems. Anaheim PD in Orange County CA still has a 9C1 Caprice in their motorpool (presumably a '96). It's been seen by my wife patrolling Anaheim Stadium. Its pretty damn beat, but still not beat enough to retire it. I'm assuming its gotta be up there in mileage though.
