 * Robin's is based off Jeff Burton's #99 Exide Batteries Ford Thunderbird from his days with Roush Racing.
 * Maurice's is based off Matt Kenseth's #17 DeWalt Ford Fusion from his days with Roush Fenway Racing.
 * Barry's is based off Robby Gordon's #31 Cingular Wireless Chevrolet Monte Carlo from his days with Richard Childress Racing.
 * Darin's is based off David Ragan's #6 UPS Ford Fusion from his days with Roush Fenway Racing.
 * Felipe's is based off Juan Pablo Montoya's #42 Target Chevrolet Impala from his days with Earnhardt Ganassi Racing.
 * Kurt's is based off Marcos Ambrose's #9 Stanley/DeWalt Ford Fusion from his days with Richard Petty Motorsports.
