In "Obama Wins!", he is seen advertising his vehicles and conducting a sale at his car lot called 'Roctvember Sales Event'. As people pass by his lot, or conduct their affairs at neighboring businesses, he is shown to unsuccessfully persuade them to visit his car lot. In the end, the boys, the Park County Police Force, General Tso, and Eric Cartman visit Stevenson's Hummer to locate the missing election ballots. The salesman naively mistakes this predicament as a sudden rush of clients, citing it to be a 'sales rush'.
The Hummer salesmen returns in "Handicar" where he is seen trying to compete in the Wacky Races.
The Hummer Salesman wears brown dress shoes, black business pants, a black belt with a gold buckle, and a blue shirt with a blue, striped tie. He has wavy, light brown hair and a similar colored goatee. His shirt has a tag saying "HUMMER" in red letters.
