Now retired, he competed in the NASCAR Nationwide Series and was a winner of the Roush Racing: Driver X competition.

He moved up to a late model car in 2000 and won the track championship and the Rookie of the Year award.

He also attended the University of Virginia's College at Wise in 2003–2005 but put his collegiate pursuits on hold as his professional racing career took off.

In 2002, he won the UARA late model touring series national championship.

In 2004, he won the Food City 250 at his home race track of Lonesome Pine Raceway in Coeburn, Virginia.

After O'Quinn's NASCAR career stalled, he moved back to Virginia to help run the family trailer business.
