The car, bearing the identification plate VIN0001—the very first Hellcat off the line—will get a Viper-exclusive Stryker Red paint job, Hellcat badges, a special documentation package, and extra one-off memorabilia, says Chrysler.

The auction will be held at the Mandalay Bay Hotel & Casino in Las Vegas September 27, on the last day of the Barrett-Jackson auction event that runs September 25-27.

Auction proceeds will go to benefit the Opportunity Village organization, which also operates in of Las Vegas, helping people with intellectual disabilities.

“The 2015 Challenger Hellcat is already guaranteed to be one of the hottest cars that will roll through the Barrett-Jackson auction lanes in decades to come,” said SRT and Dodge brand president and CEO Tim Kuniskis. “The VIN 0001 being auctioned this year is the ultimate one-of-one collectible 2015 Dodge Challenger, as Dodge is ensuring there will never be another one like it.”
