| 2010 | 4dr Sedan 268-horsepower 3.5L V6 7-speed shiftable automatic RWD |
This car has a very small back seat. If you want to carry passengers for a long distance, get an E class. see full Mercedes-Benz C-Class review |

The seat causes no discomfort to my tailbone like many ohter cars. Furthermore, the padding is firm and feels like it will last a long time. see full Mercedes-Benz C-Class review |

Not much leg room when compared to other luxury entries. No flat floor so a 3rd passenger in the rear is not possible. see full Mercedes-Benz C-Class review |
