On a sunny Saturday afternoon in the country, George and The Man normally wash the cars, The Man's big car and all of George's toy cars. But today they are doing something a little different and getting the car washed, at the country town's new automatic car wash. George and Allie are fascinated by how the car wash works and how it pulls the car through a line of different operations in a set order. When they get home, George and Allie decide to build an automatic car wash of their own to wash George's toy cars.
