The fifth Gumball 300 rally was held in May 2003, with more than 100 cars beginning in San Francisco, California with a finish line in Miami, Florida. The rally passed through Reno, Nevada; Las Vegas; Tucson, Arizona; White Sands, New Mexico; San Antonio, Texas; Houston, Texas; and New Orleans, Louisiana. Featured entrants included Jackass Ryan Dunn racing a rental car alongside skateboard legends Tony Hawk and Bam Margera in a Dodge Viper, Bucky Lasek, Motocross World champions Travis Pastrana and Carey Hart, and supermodel Jodie Kidd. Cars included a mix of Ferrari F50s and 360s, Lamborghini Murcielagos, a Koenigsegg CC and Jesse James customized VW Eurovan. Alex Roy and Dave Maher won the Gumball Spirit Trophy in his Team Polizei BMW M5, outfitted with German Police equipment. Top Gear reported that the Koenigsegg CC8S holds the fastest speeding ticket in the world, which allegedly occurred in May 2003 in Texas. It was supposedly 242 mph (389 km/h) in a 75-mph (120 km/h) zone. The Fastest Wheels award was presented to Rob Lonman Kenworthy in a Porsche GT2, with the Special Award presented to Richard and Sue Rawlings, owners of a heavily modified Chevy Avalanche.
