We’ve seen the Factory Five GTM finished in every way imaginable. From mild to wild, the GTM can be found as a barebones racer, a spec’d out luxury touring car and everything in between. This 2012 GTM offered for sale on eBay checks every box in the performance category, and doesn’t leave anything to be desired in looks either.

The GTM is powered by a GM LS 6.0-liter engine and mated to a Porsche G50-3 five-speed transaxle. The hungry LS engine is force-fed 10 pounds of boost by a Magnuson supercharger. The seller states that the engine has been built to work with the supercharger (which typically involves a lower compression ratio) and produces 550 wheel horsepower. The Corvette C7 braking system was also built up with DBA rotors, powder-coated calipers and a Wilwood brake bias dial. Lightweight wheels and sticky tires were added and custom coil-overs were built specifically for the car by Koni. The GTM also has electric power steering that can be switched on and off, a perfect touch for a street-legal racecar.

On the exterior, the car has a front splitter, side skirts, rear diffuser and motorized spoiler, all done in carbon fiber. Custom multi-color paintwork gives the GTM a different look on every corner.

It’s clear that no expense was spared on this build and the seller states that over $100,000 was invested (and we believe it). The average value for used GTMs is between $70,000 and $90,000, but this seller’s reserve is probably closer to $100,000. See all the details here on eBay.
