Owner Bio: Jeremy Wyborney
Jeremy (shown with his wife, Kimberly, and his son, Derek) is a 29-year old product development specialist. He’s been racing for four years and bought his Firebird in 2003 because he "liked this particular body style and got it for a fairly decent price." It’s special to him because, "It was my first frame-off restoration and was very challenging. I had a lot of fun restoring it, and even more fun driving and occasionally racing it." His favorite moments in the car include "thumbs-up my family and I get every time we go somewhere in it. It definitely gives me a sense of pride in the work I’ve done to it." Jeremy currently owns an ’04 Grand Prix, and in the past he’s owned a ’66 GTO, an ’84 Fiero, and an ’84 Grand Prix.
