 I just sold my 2009 C300 Sport after two years and 80,000 miles of driving.I bought it new, religiously followed the maintenance schedule and replaced the Continental tires with the same every 30,000 miles.This car was flawless in every way.Nothing ever broke, and it never needed anything beyond regular maintenance, which for 80,000 miles is very impressive indeed.The car was fast enough, fun to drive, and extremely comfortable, even on the two occasions when I drove 1,100 miles in a single day.Best thing to say about it is that I traded it in for a new 2012 C250 Sport sedan, and expect the same great service from the new one.I was sad to see it go.
