I bought a 07 C230 and the only complaint is that the brakes squeal sooooooooo loud backing out of the driveway (really embarrasing). I have taken it to the dealership twice now and the problems still exist. Not sure if I will buy another MB because of this. Trust me, I love the car, hate the brakes

 

that 19-20 was me flooring the car constantly drifting blah blah blah just havin fun... drivin it pretty much hard as possible (i can do that kinda thing since we kinda live out in the middle or nowhere) but yeah i usually get about 29.... 26 on short trips....31-32 interstate

 

I have a c230 kompressor with 80,000 miles. It has been running really rough. I have replaced the O2 sensor, maf sensor and now I am trying to replace the Knock sensor and can't find it on the engine. Help, please.
