If this special edition Camaro looks eerily familiar to you, it's because this car has been around for a number of years now. It's called the 2010 Chevrolet Camaro GS Racecar Concept and it was built by Riley Technologies and General Motors' High Performance Vehicle Operations as one of four customized Camaros at SEMA 2008.

Four years after wowing the crowd in Las Vegas, the Camaro GS Racecar Concept returns to the headlines because it will be up for sale at the Mecum Auctions next month as part of the Monterey Car Week.

The car draws inspiration from a particular racer from the past, specifically the 1969 Camaro Trans-Am racecar driven by Mark Donohue. The Camaro GS Racecar Concept was even painted in the same deep-blue paint scheme that comes with accented yellow graphics, a yellow-painted interior and yellow racing wheels.

In addition, the prototype also had its seams welded to go along with carbon-fiber fenders, doors, hood and trunk. A 3-inch exhaust system with aftermarket mufflers took the place of the stock equipment, while the car's standard LS3 V-8 engine was fitted into solid engine mounts and mated to a close-ration six-speed manual transmission.

Organizers at Mecum Auctions don't have a specific price for the one-off prototype, but they do estimate the hammer falling in the low-to-mid six digits.

2014 Chevrolet Camaro

The current Camaro SS was unveiled in 2009 and, for the 2014 model year it is updated with some minor exterior changes, like a louvered heat extractor placed on the center of the hood, a thinner grille featuring only vertical bars, a larger air intake and a significantly larger rear bumper insert.

Under the hood, the model keeps the usual 6.2-liter V-8 engine with 426 horsepower and 420 pound-feet of torque. The engine is mated to a standard six-speed manual or an optional six-speed automatic and will sprint the car from 0 to 60 mph in just 5 seconds.
