Following its build, the final Challenger SRT Demon will go to an upfitting center for the final stages of assembly. This specific car will be hand-painted in an exclusive Viper Red hue, and will be fitted with 18-inch wheels, drag radial tires and a unique VIN instrument panel badging.

Why Viper Red, you ask? That's because this specific Demon will be auctioned off at Barrett-Jackson, paired with the final 2017 Dodge Viper coupe. It's part of "The Ultimate Last Chance" auction, where the highest bidder will have a chance to take home the final examples of both cars, with all proceeds from the sale being donated to the United Way.
