OWNER BIO: Mike Davis
This '66 GTO was Mike's first car. "I drove it to high school," he says. "I originally built it with my father. It was completely built in my two-car garage--all the machining, rearend, body, paint, and welding I did myself." Now 37, Mike has been a professional bull rider and is currently a pro horse trainer and real-estate broker. But even more important, he has been racing for 18 years. His favorite moment in his GTO was winning the '03 NSCA/NMCA world championship. The Goat is also a multiple show winner.
