"The Jeep is a manly device. And a womanly device. An American device. It’s a fitting instrument to transport the free people of a free nation with the respect to which we are entitled and the dignity that we deserve. Okay, we’re a little crazy to have a Jeep for a daily driver. But if we go off our meds, we might wind up in a Prius"-P.J.O'rourke
