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 |
