Frankie scores a stadium assignment at the Super Bowl thanks to the confidence she's gained from driving around in a brand new car. Speaking of the Passat, Frankie realizes that everyone in her family has been using it. She's upset at first, but then realizes that having one nice thing has brought them closer as a family. They've basically become the Donahues.
When Nancy Donahue calls to say they are coming home early, the entire Heck clan scrambles to clean up the car they stole from their neighbors. Wrestling Matt also pitches in. It's the only way he could corner Sue long enough to confess that he was planning to say "I love you" to her on Valentine's Day.
Frankie has no choice but to come clean when the Donahues notice a scratch on the Passat. Much to her surprise, the real new car owners aren't the least bit upset. They really are terrific neighbors. As for Frankie, she also does her best to be neighborly at the big game even though she got stuck working at the portable toilets. Instead of attending one Super Bowl, Frankie ends up hanging out at eight of them!
