Chrysler's (and FIAT's) CEO Serigio Marchionne has decided to put his custom Dodge Challenger SRT8 up for auction at Barrett-Jackson. The car is painted in balck with Dark Charcoal racing stripes and tinted taillights. It also features adjustable suspension and 20 inch matte black alloy wheels as well as a sports exhaust system. No performance upgrades were applied to the engine but the original SRT8's 6.4-liter V8 produces 470 hp and 636 Nm of torque. The car will go on auction next month. More pictures in the gallery below.
