Welcome to Butler, Missouri, where the wheeling and dealing at Max Motors never stops. Owner Mark Muller is an old-fashioned businessman with an unorthodox style that always shocks and scares his baby brother, Chicago radio legend, Erich "Mancow" Muller, who's a partner in Max Motors. Despite Mancow's pleas to play it safe, Mark promises his staff he'll blow up a car "like in the movies" if they meet their monthly sales goal.

Max Motors' ace salesman, "Cowboy" Matt Harvey is in trouble with the law and turns to Mark for help. If Matt can clean up his act, and get into riding like he did back when he was a professional bull rider, Mark will bail him out. Meanwhile, Mancow learns the hard way how to do business in Butler when he spends a day out with the repo team.

In an attempt to bring some big city pizzazz to the dealership, Mancow bets Mark that a "Midnight Madness" sale will generate a ton of business for Max Motors. What Mancow doesn't understand is that things work a whole lot different in the country. Meanwhile, Mark hires a new personal assistant, Jason, who has to deal with being "the new guy" at work.

When Mancow shows up in Butler with a toy drone, Mark hatches a plan to throw one of his most creative sales promotions ever–it's an elaborate scheme involving aliens, UFO's and out-of-this-world prices. But will the staff meet the challenge set by the boss?

In order to create buzz at the dealership, Mark collaborates with the local Sherriff's department to host a gun buyback event where the community can trade in their unwanted weapons for cash. Old and dangerous weapons are destroyed on the spot and Mark adds a couple of beauties to his private collection. Meanwhile, Mark's son, Max turns to his father for a job. Against his better judgment, Mark gives him a shot.

When Mancow calls Mark with an opportunity to buy his dream car–a 1957 Black Cadillac convertible, Mark immediately flies to Chicago to seal the deal. Back at Max Motors, Rod is left in charge of the dealership and realizes it's not that easy to be the boss.

With a bunch of old trade-in cars destined for the scrap yard, Mark gets an idea to motivate the sales staff and have some fun. His three top salesmen that week will get to ride against him in a demolition derby contest. But when Mancow finds out that Mark hasn't included him to competition, he takes matters into his own hands.

Mark hosts an evening of cage-fighting at the Max Motors lot to sponsor Mongo's return to the sport while also attracting huge crowds to the dealership. As Mongo trains for the fight of his life, Mancow sees an opportunity to cash in as his new manager. Meanwhile, Larry's sanity is stretched to its limit trying to organize the big event around Mark's increasingly steep demands.

The dealership is forced to scramble when their weekend sales event falls through. At the last minute, Mark decides to host a Veteran's Appreciation Day, leaving Larry in charge of planning the logistics. Meanwhile, Amy bets Mark that he can't go a week without buying another car for his personal collection, and Mark tries his best not to cave in to temptation.

Mark and his son Matt decide get into the moonshine business, and enlist the aid of Butler's best brewers. But to get Erich on board, they'll have to prove to him that moonshine isn't just for local folks. Meanwhile, Jason struggles to balance his duties for Mark while also training Mongo for his upcoming cage-fights.

When the rodeo comes to Butler, Mark is caught under-staffed during the busiest weekend of the year, forcing him to recruit his wife Amy and their three sons to work the dealership. Meanwhile, Erich butts heads with the local radio station when he brings his big-city shock-jock radio show to small town Butler.

Mark's mother is in town to spend some quality time with the family. But Mark is so overwhelmed with getting the dealership's old trade-ins to one of Missouri's biggest auctions that he can't find time for his mother. Meanwhile, Erich must cover for Mark by showing their mother what Butler has to offer.

Construction has commenced on the Max Motors lot and brings business to a standstill. Mark shuts things down at the dealership and invites Erich and the boys to a work retreat Max Motors style. Meanwhile Larry and a skeletal crew secretly prep for the Five Dollar Car Sale!
