The world’s most prolific Dodge Viper collectors, the Rauhs of Arp Texas, have added the last unit ever produced to their portfolio.D’Ann and Wayne Rauh collected their bronze gold Viper at Chrysler’s Conner Avenue assembly plant in Detroit last week.The Rauh collection tallies an impressive 40 units. Dodge boss Ralph Gilles was on hand to surrender the last Viper ever built to the Rauhs. Considering the their fascination with the truck-powered American supercar, it seems quite fitting to have the last Viper produced making its home at the Rauh’s Snake Pit in Arp, Texas.The Rauh’s Viper was the very last 2010 model to roll off the production line and features custom bronze gold surfacing embellished with Viper-significant racetracks airbrushed into the car’s finish. Unique five-spoke alloy wheels further differentiate this very last Viper from its SRT10 siblings. The brainchild of motor industry maverick Bob Lutz, the Viper heralded a peak of reckless design at Chrysler when it debuted back in 1992. A tubular chassis, outrageous styling and an oversized petrol converted V10 truck engine (which grew from 8- to 8.4l during the car’s lifecycle) endowed the Viper with Corvette-humbling performance.As Chrysler’s economic fortunes waned in the last few years the Viper, strangely, saw a proliferation of special edition models. Chrysler has been trying to find a buyer for the Viper brand since late 2008, yet few could be lured into committing cash to develop a new Viper. A fundamentally redesigned Viper is rumoured to be due in 2013.With Fiat now running the show at Chrysler, one can hardly envision a state of affairs where the Italian company (holding Maserati and Ferrari in its portfolio) will commit resources to developing an American competitor for its home-grown supercar brands. In all probability 2010 will signal the swansong for the famous Viper brand. Fans of the America’s wildest supercar will be thoroughly upset by its demise.At least the legend lives on in the record books, as the Laguna Seca production car lap record is held by one of the few Viper SRT10 ACRs produced last year.
