The vehicle repair industry makes a ton of money on stolen cars.
The average repair cost of stolen vehicles locally is something like $3500. Some dealerships and repair shops need the business to survive, and there is no incentive to stop it.
Short story:
Christmas one year my wife and I went shopping, and decided to go for dinner on the way home. Parked, walked 50 ft to restaurant, line up too long, went back to van to find it gone, with gifts. We're talking under 2 minutes!
Later that weekend cops phoned to say they chased our van, rammed it,thieves ran and they grabbed 'em, claimed the house breaking tools they had were ours (!) They spent xmas in jail, but could NOT BE CHARGED WITH CAR THEFT because the police did not see them steal anything. They were charged with possessing something stolen of value over $5000. Charges were later dropped due to lack of interest.... violent crimes more important.
I picked the van up, as directed by the police. On the way home the sliding door fell off!
