Mercedes-Benz makes the best seats in the business, period. Even after a 10 hour drive, my back did not hurt.
Smooth, but firm. There is a certain solidity in a Mercedes-Benz that other cars just cannot match.
There is a bit of wind-noise, but road noise is well muted and the engine, while quiet, makes a very pleasing roar when you step on it.
This car is tight, far tighter than the previous generation C-Class. Feels like a bank vault, the way Mercedes-Benz cars used to.
This is my third C-Class. These cars are always reliable and comfortable, but with the new model, they are also (for the first time) gorgeous.
