Sparky is a high-spirited sports car who's sick of his boring life. He wants to hit the highway and explore the world, but first Sparky needs a GPS. Then earn some money and buy one, demands his father. Only problem is: there aren't many jobs in El Coche. For a few days, Sparky works at his fathers Gas n Go, but eventually the pressure gets to him. Dads can be so unreasonable! So Sparky takes a job with the duplicitous Diesel, who's busy selling bum gas, slipshod retreads, and snake oil valve goo, all at outlandish prices. Its a dreary gig. Worse, thanks to Diesels accounting chicanery, Sparky finds himself deeper in debt every day. Desperate to break free, Sparky agrees to work at Diesels Greasy Springs Circus, a cruel coliseum where cars are pitted against each other in battle-to-the-death contests. Sparky ends up racing for his life on the Wheel of Misfortune while all of El Coche looks on in horror. Sparky realizes that there are fates worse than boredom.
