A vibration felt through the center floor of the vehicle can be caused by driveshaft flex discs, which crack and shred, causing excessive driveshaft movement. Not repairing these can cause damage to the driveshaft center support bearing, or, in the worst case scenario, damage to the transmission or differential.

Due to the size and material used on the brakes of these vehicles, the brakes may start to squeak around the 50 percent wear point. The brake rotor surfaces become uneven, causing a lip to form at the outer edge of the rotor.

The Mercedes C300 is a solid, comfortable, and capable car. Hate the tire pressure monitor, but only because it's accurate. I have had problems with the lights that I shouldn't, so that's not great reliability for a new car. The interior trim does look and feel cheap in places, and I'm not convinced it's well made.
