TREMENDOUS MILEAGE Records of Ioo,ooo and 200,000 miles almost wholly free from repair give vivid emphasis to this owner verdict: That the Willys-Knight provides lux urious riding comfort with economy of service year after year. It is the Willys-Knight Sleeve-Valve Motor which provides this tremendous mileage. Study the design. No tappets; no valve-heads to check the in-rush and exhaust of gas; no clicking springs to weaken; no cams to hammer and wear out. COMPRESSION' 0TER nMEiEXHAUST No Other Motor Has Cost so /* \ Little, Runs so Smoothly ** N. at the 50,000th Mile o.* «x, r,.* *>, ,«*'' ~. -< But instead: Wide free ports for the gas in metal sleeves which slide noise lessly on a film of oil. A big, round combustion chamber with center-fire spark where every drop of gas is turned into power for your use. The little carbon that forms helps to seal com pression more tightly. The stalwart chassis matches the age-resisting motor. The coachwork completes the car's perfections. Thus luxurious travel becomes a continuous economy with the Willys-Knight.
