When our friends Manley and Dana came to visit last week, he rented a Kia Rio. When Manley honked the puny little horn with his key remote, everyone laughed. But when he pushed another button and the insertion part of the key flicked out like a switchblade knife, Manley said, “They might laugh when they hear the horn, but when I pull out this key they’ll shout, “Run! He’s got a RIO!”
