Rudy Russo is a young and cunning used car salesman in Phoenix with aspirations of running for senate. He works at the struggling New Deal used car lot owned by the elderly Luke Fuchs, who agrees to help invest $10,000 in Rudy's campaign if he promises to keep the business alive. Meanwhile, across the street, Luke's younger brother Roy L. Fuchs (also played by Warden) is desperate to keep his used car lot from being demolished and replaced by a proposed freeway exit. Wanting to collect life insurance money and New Deal from Luke, Roy hires his mechanic, ex-demolition derby driver Mickey, to recklessly drive Luke's 1957 Chevrolet Two-Ten coupe around the block with Luke in the passenger's seat. After the Chevy crashes back into the lot, Luke dies of a heart attack, but leaves Rudy with evidence that Roy staged the "accident". In an attempt to prevent Roy from gaining any inheritance, Rudy has his superstitious co-worker Jeff and mechanic Jim help him bury Luke in the lot's backyard in an Edsel that was once New Deal's sign ornament. They explain to Roy that Luke went on a vacation to Miami.The next night, Rudy and his friends make an illegal live broadcast of their commercial in the middle of a football game, but it goes awry when Jeff finds out the car on display is red (which he believes is bad luck) and female model Margaret has her dress stuck on the hood ornament, which rips and exposes her when the hood is popped open. The commercial results in New Deal receiving a massive number of customers the next day. In one deal, Jeff cons a family into buying a station wagon by having the lot's mascot dog Toby fake being run over during a test drive. When Roy lures customers in his lot by hiring a circus animal service, Rudy counters with a live stripper show. Luke's estranged daughter Barbara Jane visits the lot in hopes of reuniting with him after more than ten years, but Rudy conceals the truth about her father by taking her out on a date, which inadvertently convinces her to stay in town.Rudy's gang broadcasts another commercial in the middle of Jimmy Carter's presidential address, destroying some of Roy's used cars in the process, most notably his prized Mercedes SL. In retaliation, Roy storms into New Deal and attacks Jeff before discovering Luke's resting place. Roy brings the police to New Deal to dig through the backyard the next day, but Jim has taken the Edsel out of the pit, and he rigs it to crash on a power transformer and explode. Everyone believes Luke was killed in the fiery accident, and the evidence is destroyed. Roy believes he now has possession of New Deal, but Rudy points out that Barbara is effectively the new owner. Barbara discovers the fiasco over her father's death and fires Rudy. As a final means of shutting down New Deal, Roy has his connections in a local TV station KFUK alter Barbara's commercial to imply that she has a mile of cars and pushes a trumped-up charge of false advertising.Rudy's luck changes when he wins a bet on a football game, guaranteeing him enough money for his campaign. Once he discovers that Barbara has been sent to court for false advertising, Rudy convinces her to tell the court she has a mile of cars. To avoid a charge of perjury, she must prove it in front of Judge H. H. Harrison by having over 250 cars on her lot by 2:45Â p.m. Rudy spends his senate investment on buying 250 cars from Mexican dealer Manuel and having 250 student drivers deliver them to New Deal in less than two hours. After overcoming Roy's attempt at disrupting the resulting convoy and Jeff's superstition of driving a red car, the drivers arrive in time. The total measurements are just long enough to equal a mile, saving the used car lot. Roy's former attorney Sam Slaton informs Rudy and Barbara that once the freeway ramp across the street is constructed, New Deal will become the largest dealership in town.
