When Steve Saleen launched his new company, SMS Supercars, back in 2008, he announced that he would be expanding his portfolio of vehicles to include the muscle car offerings from Chevrolet and Dodge. First up was the 570 and 570X Challenger, followed soon after by the 302 Mustang.

Now, Steve Saleen's muscle car trifecta is finally complete, as SMS officially unveiled the 620 Camaro at Barrett-Jackson this week. The car maintains the styling cues featured on both the Challenger and Mustang with an aggressive front splitter, side skirts, rear diffuser, butterfly hood and chrome 20-inch wheels. Inside is a custom leather interior, and under the hood, the 6.2-liter V8 has been supercharged to 620 horsepower and 570 pound-feet torque.

In addition to unveiling the car at Barrett-Jackson this week, SMS actually auctioned off the first production example last night. This particular car was also a special "Bondurant Edition" in honor of Steve Saleen's former racing teammate, Bob Bondurant, and the two decided to donate the proceeds from the sale to two charities: Cox Charities and the Make A Wish Foundation of Arizona.

So, how did the car do? Bidding for the SMS 620 Camaro eventually reached the $100,000 mark, meaning the two charities will be getting a significant donation and the lucky new owner just got a nice tax write-off. Did we mention a Bondurant three-day performance driving school is included with the car?
