Sometimes you have to go against the grain. In the case of the Detroit Pistons' masked shooting guard Richard "Ripâ€ Hamilton, that means coppin' somethin' foreign in a city that was built Ford tough. n "This is the city of Fords,â€ says Hamilton, whose nickname stems from his father, "Bi Rip,â€ ripping his diapers off as a baby. "But there's no pressure to ride American. Of course, if you work for Ford, they don't want you riding in imports.â€ n Hamilton doesn't always take chances, though. Just look at his newest toy, a blue 2006 Aston Martin DB9 . . . . Ford owns Aston Martin, ya dig?
