Owner Bio: Mike PlymaleMike Plymale (shown here with his twin grandsons, Samuel and Patrick Sarauer), a 52-year-old maintenance supervisor, has been racing for 14 years. He bought his '75 Trans Am in 1997 because a friend of his with a '67 GTO told him, "Buy that car." It's special to him "because it reminds me of the '75 TA in which I took my wife for our first date in 1975 and because I won four class races with it, the most recent being the 2008 Ames Performance Pontiac Tri-Power Nationals in the Tin Indian Class. Mike also owns an '02 Grand Prix GTP.
