A 2011 Dodge Challenger SRT8 392 once owned by Sergio Marchionne, the CEO of Fiat and Chrysler, has sold at auction for $175,000.

All proceeds from the sale, which took place over the weekend at a Barrett-Jackson auction in Palm Beach, Florida, will be donated to the United Way for Southeastern Michigan community group.

The car was bought by an avid collector from New York, who also received a 540-horsepower Hemi V-8 crate engine from Mopar as part of the deal.

Of course, Marchionne’s Challenger SRT8 392 was no run-of-the-mill model. In addition to its provenance and 470-horsepower rating, the car also features a few of Marchionne’s own custom details.

These include Dark Charcoal racing stripes that were hand laid by the designers at SRT, smoked tail-lights, blacked-out badges, lowered suspension with adjustable coil-overs from Mopar, and a high-flow exhaust system.

The stock 20-inch aluminum wheels were also given a matte black finish to complete the sinister look, and for the interior Marchionne chose black leather for the seats and had these embroidered with SRT and 392 logos.

If you’re wondering what Marchionne chose to replace his Challenger, SRT tells us he currently owns a Chrysler 300 SRT and a Jeep Grand Cherokee SRT.
