I bought a 2012 CLS63 CPO used in January 2016 with 40,000 miles. Paid less than half the cost of a new one and felt I got a good deal. The vehicle looked like new and runs great. In June 2016 I drove from Los Angeles, CA to Cary NC. No problems or issues during the trip and averaged 24.5 mpg. They say that "there is no replacement for displacement" and I found that out to be true. I extensively used the Distronics adaptive cruise control to control the speed and had no loss of speed going over the mountains or accelerating up on ramps. I am happy with my purchase of this vehicle, especially because the price of a new one would be beyond my budget and paying the depreciated price made owning an AMG affordable.
