There are only two Devon GTX supercars in the world. One of them was up for sale at the most recent Barrett-Jackson auction and it sold for a ticklishly low price.

The chromed-out version of the Dodge Viper that promised individuality to its lucky owner came to a hard halt when Dodge stopped producing the Viper in 2010, but with a half million-dollar price tag it’s tough to see what’s essentially the bling-bling edition of Dodge’s V10 tire shredder going very far. On the other hand, $220,000 might be a justifiable price for someone in the market for such cars, and that is what the GTX took on the auction block including buyers commission.

We had no way of guessing what the GTX would sell for just over a week ago when we reported that the car was going up for auction with no reserve, but the 60 percent discount it ended up selling for was far from our minds. Alas, such is life in the world of no-reserve auctions on items with extremely limited marketability.

It was a good idea, if only it had worked. A few years back, a man by the name of Scott Devon decided that the world needed a new American supercar. So he appointed a Swede (Daniel Paulin) to design his dream car.

Being a start-up company, Devon did not have the money to develop his own platform or design his own engines. So what he did instead was to take a perfectly good Dodge Viper, and give it some new clothes.

Actually, he did more than that as this was no mere body-kit. The car had a custom, coachbuilt body and a completely unique interior. Oh and he tweaked the Viper’s 8.4-liter, V10 motor to produce a modest 650-hp.

The end result looked very impressive, and it also worked. Thanks to its aerodynamics package, the GTX was very capable around a race track. It in fact set the fastest lap-time for a production car at both Willow Springs and the Laguna Seca Raceway. We use the ‘production car’ term loosely here, read on to find out why.

Devon wanted to put the GTX into limited production, but their plans got cut short when Dodge announced the stoppage on Viper production in 2010. This would hurt Devon’s supply if anyone wanted one. Another reason the project didn’t work was because the order books remained empty. We reckon the $500,000 asking price had something to do with that.

In the end, just two cars were produced, and now one of those can be in your collection. Lot # 1296 at this month’s Barrett-Jackson Collector Car Auction in Scottsdale, AZ., is a beautiful black Devon GTX.

We will have to wait and see what it fetches at the auction, but if you’ve been looking for something very rare and unique, this might be the car for you.

While the real stars of the Pebble Beach Concours d’Elegance are the vintage autos, the Concept Lawn is a special place where future show-stoppers are put on display. While some of the models are actually concepts, many are rare coachbuilt models and a few are full-production cars.

In the concept category there was the luxury convertible plug-in hybrid, the Fisker Sunset, as well as the absolutely stunning Infiniti Essence Concept - a hybrid in it’s own right, making 600hp thanks to a 440hp twin-turbo direct-injection 3.7-liter V6 and a 160hp electric motor.

Included in the list of Coachbuilt creations was the edgy Corvette ZR1-based Stile Bertone Mantide. This is no kit car, however, as the vehicle was designed by Jason Castriota, the man who also penned the Pininfarina P4/5. Plus, it weights 220 lbs less than the ZR1 for even more performance.

Also on display was the Devon GTX (pictured above), arguably the arch-nemesis of the Mantide, as it is based on the Dodge Viper. With a more shapely body than the Mantide, the 650hp GTX is scheduled to attempt to set a new fastest lap time at the Nürburgring. No doubt there’s some ego involved in this announcement as Devon attempted to buy Viper from Chrysler but the deal was never completed.

In the production category cars ranged from the reasonably well priced (Lotus Evora) to the ridiculous (Bugatti Sang Bleu). The four-seater Lotus is scheduled to be released early next year, while the ultra-limited edition Bugatti is based on the convertible Grand Sport model. Other production or near production models included the Spyker C8 Aileron Spyder, V-10 powered Audi R8, the 750hp carbon-chassis Aston Martin One-77, a Morgan, the all-new 510hp 2010 Jaguar XJL Supersport, the Mercedes-McLaren SLR Stirling Moss and the Rolls-Royce EX200, aka, the Ghost. And who could forget the misplaced SMS 570X Dodge Challenger.
