Owner Bio: Matthew Crise
Matthew Crise, a 36-year-old operating engineer (shown here with his son, Clayton), has been racing for one year. He bought his '69 GTO in 1990 because it's his "favorite year." It's special to him because he's had it since he was 16 years old. His favorite moments with it have been "restoring it" and racing it. Besides his GTO, Matt also owns a '65 LeMans.
