Owner Bio:Zachary Edwards
Racing for only two years, Zachary Edwards of Virginia Beach, Virginia, knew he wanted a rear-wheel drive musclecar and opted for a Pontiac-this '05 GTO is his very first. "It's great when someone rolls up to a stop light next to a car that has a commanding presence and sounds like a race car shaking the tarmac apart. That's what I wanted," he says. Zachary took first place in Mid-Class for his club at the New Age GTO Fall Brawl in November, 2006, and looks forward to winning rounds in the future. He is a manufacturing engineer, a member of the GTO Owner Association of Tidewater and enjoys modifying his GTO.
