There are several charity cars up for auction this week at Barrett-Jackson, but this custom Dodge Challenger owned by Richard Petty might just be our favorite. Built by Petty's Garage, the Challenger is painted in legendary Petty Blue and features a 426ci Hemi V8 with 585 horsepower and 560 lb-ft torque. Other modifications include hand-fabricated body components, upgraded suspension, Brembo brakes, and a center exhaust.
