Mercedes unveiled the 2007 SLR "722 Edition"

The new SLR "722 Edition" isn't going to be cheap and definitely not for slow drivers.  This beauty has an increased output of 650 horsepower, a tailor-made suspension configuration, and a much sportier interior.  It's super fast going from 0-62 mph in 3.6 seconds and reaching 124 mph at 10.2 seconds with top speed of 209 mph.
