Mercedes Benz car sponsors Golf tournaments in Slovenia. They have made removable transparent stickers with a "window hole" printed on and the headline "Golf happens". They have put these stickers on cars of competitive brands who where parked on the parking places in the surrounding of the golf tournaments. The backside of the stickers, which invites you for a test-drive in a Mercedes B, has been put under the windshields.
