 Useful features of the smaller Jeeps are their short wheelbases, narrow frames, and ample approach, breakover, and departure angles, allowing them to fit into places where full-size four-wheel drives have difficulty.After the war, Willys did not resume production of its passenger-car models, choosing instead to concentrate on Jeeps and Jeep-branded vehicles, launching the Jeep Station Wagon in 1946, the Jeep Truck in 1947, and the Jeepster in 1948.An attempt to re-enter the passenger-car market in 1952 with the Willys Aero sedan proved unsuccessful, and ended with the company's acquisition by Kaiser Motors in 1953, for $60 million.
