In Spain, it appears to be just take them.
During a press event near Montserrat, Spain a group of foreign journalists (mostly U.S.) were stopped and detained by the guarda civil trafico. Not for hot rodding the new 550 horsepower Mercedes-Benz E63 AMG or breaking traffic laws. It was for failure to produce an international drivers license. Altho it's only a technicality to have one (there's no test, it just confirms you have a license in your home country) the group of about 20 reporters were held in custody and 6 $100,000 AMG's were seized.
After several hours of negotiations between Mercedes and the local constabulary, the reporters were finally released but not the cars.
