Dodge and Barrett-Jackson have teamed up to offer a pair of lasts to one lucky buyer. The auction will see the very last 2018 Dodge Demon and the last 2017 Viper sold with proceeds going to charity. The Demon is car number 3,300 and rolled off the assembly line in Canada clad in black.

Dodge will repaint the car Viper Red and auction it off along with the last 2017 Viper. The Demon includes 18-inch wheels, Demon drag radial tires, Demon badging and a special VIN instrument panel badge. The Viper is a plain looking ride meant to remind of the original Viper RT/10 from years ago.

The Viper has carbon fiber trim on the exterior, Alcantara seats, and a 645 Hp 8.4L V10 engine. All proceeds from the auction will go to the United Way. There are no estimates on what the auction will bring money wise.
