This is one of the benefits of 'personal ownership' of police cars. It used to be EVERYONE had a motorpool and you were assigned a car when you came on shift.
Cars weren't taken care of, nobody cared about the cleanliness or the maintenance, and cars had to be replaced frequently.
Don't know which department started it, but they deserve an award for thinking of it. Buying (or leasing) MORE cars so an officer could be assigned his or her own car. They take it home, they take care of it. The cars last much longer, and I've never seen a dirty police car in any department that does it.
Cars are well maintained, last years longer than they used to, and when done are worth much more when sold/ traded in/ or returned on lease.
I used to live in a neighborhood in Solomons and had three or four cops next door/ on the street. These people take a LOT of pride in their patrol cars. I'd see them what seemed like DAILY out there cleaning their patrol cars, vacuuming and cleaning the interior, scrubbing the tires and wheels, waxing/ polishing, and constantly cleaning the windows, while their personally owned cars went weeks and months without getting washed. I like the idea of them taking their cars home, and it seems to be working just the way it was intended, and saving the taxpayers a massive amount of money.
$10 for a car wash? I bet it came out of their own pocket.
