- When John Andretti was released from the Richard Petty #43 midway though the 2003 season DEI announced that they would field an extra car for Andretti at the Brickyard 400 in car #81. After the announcement, Andretti was hired as the interim driver for the #0 NetZero car for Haas racing.
After running a few races with Haas, Andretti drove the #81 for DEI at Indy, but this left no driver for the #0 car. Jason Leffler was named as a last minute replacement, and this would breach Leffer’s contract with his Truck series team. The ordeal would eventually lead to Leffler being fired and taking over the #0 for the remainder of the season.
This left Andretti without a ride. He quickly was picked up by DEI to drive the #1 Penzoil car for the remainder of the season, despite a last place finish in his one-off race in #81.
