Used Cars (1980)
Used car salesman Rudy Russo needs money to run for State Senate, so he approaches his boss Luke. Luke agrees to front him the $10,000 he needs, but then encounters an "accident" orchestrated by his brother Roy, who runs the car lot across the street. Roy is hoping to claim title to his brother's property because Roy's paying off the mayor to put the new interstate through the area. After Luke disappears, it's all out war between the competing car shops, and no nasty trick is off limits as Rudy and his gang fight to keep Roy from taking Luke's property. Then Luke's daughter shows up.
