Jerry plans to buy a car with an insider deal from Puddy, who's been promoted to a car salesman. George warns Jerry to watch out for 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." 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 candy bar. Only he can't get one from the machine with a crinkled dollar so he asks a mechanic (who he knows has a crisp dollar) for assistance and is refused service. Finally, when he gets the correct change, the Twix bar hangs. With his errands run, Kramer's next test is to take the car to the limits of its fuel tank. Irritated (when isn't he), 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. Elaine and Puddy have a fight and break up. Jerry's insider deal is off. George confronts the mechanic. Jerry wants George to help him get a good deal; however, George is only interested in getting back at the mechanic. 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. Elaine and Puddy get back together and Jerry is going to get his deal, until Puddy says "high five me" to Jerry, one time too many. Kramer and the salesman, with the dealership in sight, decide instead to go for it.
