Jerry plans to buy a Saab 900 NG convertible with an insider deal from David Puddy, who has been promoted to a car salesman. George warns Jerry to watch out for deceptive car dealers.
Kramer takes the car Jerry is planning to buy for a test drive with another salesman. Elaine returns from a lunch with Puddy at Arby’s. Puddy offers Jerry a “high five”. Elaine brags about her new “salesman boyfriend” taking her out to lunch. Jerry asks where they went, and Puddy chimes in “Arby’s”. Kramer misses the turn to go back to the dealership; instead, he plans to give the car a full test of a Kramer daily routine.
Hungry, George seeks out something to eat and must settle for a vending machine Twix candy bar. Only he can’t get one from the machine with a crinkled dollar bill so he asks a mechanic (whom he knows has a crisp dollar) for assistance and is refused service. Finally, when he gets the correct change, the Twix bar fails to drop and merely hangs from its perch. With his errands run, Kramer’s next test is to take the car to the limits of its fuel tank. Irritated, George seeks assistance from a salesman. When they return to the machine, the Twix bar George had hanging and the one behind it are gone. George suspects the mechanic took them. Elaine and Puddy have a fight and break up. Jerry’s insider deal rapidly becomes less favourable, as Puddy starts ringing up a long list of miscellaneous charges for “extras”, and changes the color of the car to yellow because “I can’t give you black at that price.”
George confronts the mechanic, insisting that he got two Twix bars because he sees cookie crumbs on his face, and argues that “Twix is the only candy with the cookie crunch!” The mechanic claims it was a 5th Avenue bar and that the cookie crumbs were actually nougat crumbs. Jerry wants George to help him get a good deal; however, George is only interested in getting back at the mechanic and that he is terribly hungry. The car salesman riding with Kramer really gets into driving below empty. George tries to complain about the mechanic, but gets into a debate about candy bars. In an attempt to get a great deal on his car, Jerry tries to put Elaine and Puddy “in a relationship today”. George sets up a candy bar lineup, to implicate the mechanic, only to find his lineup being eaten by the dealership staff (including the mechanic), making him more frustrated and claiming “it was a set up” and screaming “Twix!”, parodying Star Trek II: The Wrath of Khan. Elaine and Puddy get back together and Jerry is going to get his deal, until Puddy says “high five” to Jerry, one time too many. Kramer and the salesman, with the dealership in sight, decide instead to go for it in the manner of Thelma and Louise. The car however, soon rolls to a stop. Kramer exits the car after saying, “Well, I’ll think about it.”
