How it came to be is unclear, but Bloomfield Hills, Michigan is actually using a Cadillac XLR-v as a police squad car.
Granted, Bloomfield Hills is considered a tony suburb of Detroit. But, still. Sticker on these is about $100,000. Granted, they’ve been slow sellers, but we didn’t think Cadillac had become this desperate.
The real story behind it is unknown.
It may just be a publicity stunt, like those Dare Corvettes that a handful of police departments have used. Or maybe it was forfeited in a drug bust. Whatever the story, one thing is clear:

Whichever officer is assigned this car is going to enjoy his or her work.
