Just about every C-Class we've ever tested has been smooth, quick, quiet, and comfortable. Dynamic characteristics include agile handling, along with excellent steering and brakes. You can also usually count on a quiet and supple ride, as well as firm but very comfortable front seats. However, our 2001 model also demonstrated frustrating ergonomic quirks, including confusing and cumbersome controls. The audio and climate systems, for instance, are confusing (although audio switches on the steering wheel help). It's also easy to hit the cruise-control lever when you reach for the turn-signal lever.
