"This trend has crept up on as and is clearly on the increase, for quite obvious reasons because it's difficult to steal these cars," says Daniel Löfgren at the Stockholm Södertörn police to the news agency TT.
He explains the cars are usually expensive, priced at $60,000 or more, and cites Porsche Cayenne, Subaru and Audi RS-models as examples. Many are capable of high speeds and have large trunks. All this makes them ideal vehicles for committing other crimes.
"They need large engines so they can more easily get away from the police in a car chase," says Löfgren.
The police officer has little advice for car owners on how to protect themselvs. "It's difficult. These guys are on the prowl for the cars they want. You can't exactly hide a car."
