Growing up, Jim Walton worked for his Dad at Wal-Mart sweeping stores and stocking shelves. Today, he presides over the largest family empire inside a non-descript building in Bentonville, Ark. that he shares with around 20 employees. For Walton, vehicles are a means to an end. This might explain why his daily driver is a 2002 Dodge Dakota pickup. When payload capacity is of concern, Walton might drive his 1999 Chevrolet Silverado pickup to the dump. But most days, he prefers his Dodge Dakota or 2000 Acura Integra, a nimble vehicle that returns superb fuel economy.
