After leasing the C63 for a few years, we bought ours out because we had very low kms and the residual wasn't that high. We even gambled on not getting the extended warranty for a few reasons. One - the headbolt issue affects mostly early 2011's and earlier vehicles. Our car was a 2011 but with some research was outside of the range. Two, we had also had a C350 earlier (same generation) and reliability wasn't bad...mostly light bulbs burning out and nothing major as far as repairs. As far as maintenance, costs can be high especially if you go to the dealers but if you shop around , prices for consumables (tires, oil, brakes, etc aren't that bad). Regarding the article, the Speedshift MCT transmission didn't come until the 2012 cars (with the interior revision). Before that, it was the regular 7gTronic with rev matching. Extremely fun car to drive though - we'll see how it lasts over the years.
