The sole Dodge Viper GTS CS in existence is going up for auction early next year.
Created as part of an effort between Carroll Shelby and Fitzgerald Motorsports, the Viper GTS CS features a unique exterior with a Cobra-inspired front end, custom side vents and eye-catching 18-inch wheels.
The bold design continues in the cabin where there are red and gold leather seats with four-point harnesses. There’s also special sill plates and embroidered Carroll Shelby signatures.
Bigger changes occur beneath the skin, as the Viper has been equipped with a modified intake, an upgraded computer and a performance exhaust system. Other highlights include high-performance plug wires and a revised rear end with 3.73 gearing.
Thanks to these modifications, the 8.0-liter V10 in the Series I Viper GTS CS was slated to produce 480 hp (358 kW / 487 PS) – a slight increase over the model’s standard output of 450 hp (336 kW / 456 PS).
There were plans to build 50 Viper GTS CS’, split evenly between coupes and roadsters, but that idea was scrapped due to Shelby’s declining health. As a result, this is the only model that was ever made.
This is the first time the car has been offered for sale as it has remained in the hands of its original owner for decades. However, it is well documented and comes with a signed letter of authenticity.
There’s no auction estimate but, when it goes up for grabs at Mecum’s Kissimmee auction in January, it will likely exceed its originally intended price of $89,900 (£67,573 / €75,170).
