The Dodge Viper has officially ceased production, while 2018 Dodge Challenger SRT Demon is on a limited run. Both cars are for die-hard American car enthusiasts, and there will be a chance to own them both as a package.

The last unit of both cars will be actioned together as one lot called “The Ultimate Last Chance” at the Barrett-Jackson Northeast auction, taking place at the Mohegan Sun in Uncasville, Connecticut on 20 June, with 100% of the sales proceeds benefiting The United Way. The two vehicles are painted in an identical shade, Viper Red, and are built with specific dash plaques and custom car covers and come with an authentication kit. The Viper is based on the very first Viper from 1992, while a Demon crate engine that is good for the drag strip will be offered to the winning bidder.

There’s no doubt about the performance of these two. The 645 hp Dodge Viper is powered by 8.4L-litre V10 engine featuring carbon fibre body. The 840 hp Dodge Challenger SRT Demon is built for drag racing. With a 6.2-litre  HEMI V8 engine and 20-plus industry-first drag performance related features, it accelerates from 0-60 mph in just 2.3 seconds.
