At the end, the couple that were looking for directions to the Interstate, end up all dusty and still looking for the Interstate. While credits roll, a series of short postscript scenes show the resurrection of the town, like cars are now passing the town, Flo's V8 café is full of customers, customers trying out Ramone's body art, Guido's tire shop is full, a museum of Doc Hudson's racing days opens, Sarge opens a boot camp for off-road vehicles (who have never been off-road), the reopening of the Wheel Well Motel, etc. One of them is the reopening of the Radiator Springs Drive-in Theater, where they show movies of previous Pixar productions but in a car context, like Toy Story (in the marquee it's Toy Car Story), with the actual voices of Tom Hanks and Tim Allen, Monster Trucks, Inc., with the voices of John Goodman and Billy Crystal (Goodman is worried about the Boo mobile), and A Bug's Life, with the voice of Dave Foley. As an additional in-joke, Mack the truck praises the performances of Hamm in Toy Story, the Abominable Snowplow in Monster Trucks, Inc., P.T. Flea in A Bug's Life, which are all voiced, of course, by John Ratzenberger. Mack's final comment is they're voiced by the same actor and "what kind of cut-rate production is this" to reuse the same actor.
During credits, Mack (John Ratzenberger) watches car-versions of earlier Pixar hits, commenting on the fine actor in each scene before realizing it's the same actor (John Ratzenberger) playing different characters in each movie. There is an additional scene at end of credits, as with last year's Chronicles Of Narnia.
