CEM debuted at the 2004Coca-Cola 600 with Kevin Lepage driving, finishing 43rd after suffering overheating failures. After running four more races with Lepage, all resulting in DNF's, Tony Raines took over the driving duties, his best finish being 28th at Dover. In 2005, ARCA racer Stuart Kirby began driving, qualifying for seven races, posting a best finish of 31st. Mike Garvey drove for the team in 2006, but after Joe Auer became concerned with the lack of performance and under funding, the team decided to allow Petty Enterprises finish off their obligation. It was said that Auer decided to quit racing in favor of watching his son during the key years of his baseball career. It was quite the rise for this team who went from part-time short track racing outfit to regional races and finally the top of the class in the Cup racing league.
