The 2018 Dodge Challenger SRT Demon is an incredible vehicle. While it's not amazing on turns, it's a monster on the tracks. On the other side, we see the Dodge Viper, which is a respectable car in its own right, despite its small success. This summer, you'll have a chance to purchase both of them in a combo-style two-pack. Or to participate in an auction for them, at least.

In an announcement by Dodge. The two vehicles will be offered together at this June's Barrett-Jackson auction. They will share the same red coat of paint, and will come with special badges, VIN documentation, and “one-of-a-kind memorabilia.” To add a noble touch, the proceeds will then be donated to the United Way.

Steve Beahm, FCA’s head of cars in North America, remarked on the opportunity in a statement.

“An avid collector could search a lifetime to try to put two vehicles of this pedigree together and never find it, it’s that elusive. Pairing the last Dodge Challenger SRT Demon and the Dodge Viper production cars – two of America’s most sought-after vehicles – under the roof of Barrett-Jackson gives someone the ‘last’ chance to own this unique piece of automotive history, and Dodge//SRT the opportunity to raise money for a cause close to our hearts.”

There's no word on what to expect the auction to go for. But given that both vehicles are rather costly in their own right, it'll be a hefty sum. It's for charity, though.
