Knapman had a background in kart racing and other racing forms that spanned many years before his time in CASCAR.
Elvis' first CASCAR race was on April 19, 2002, when he was 16 years of age, which made him the youngest driver ever to compete in a CASCAR-sanctioned event. He finished nineteenth. On May 24, 2002 he suffered serious injuries in a horrific 2 car crash while running in third position. He made a surprising return to CASCAR just over a year later at Delaware Speedway in Delaware, Ontario on June 13, 2003, finishing sixteenth, but hasn't raced since.
