| 2008 | 4dr Sedan 420-horsepower 4.2L V8 6-speed manual AWD |
Rear seats seem very cramped for leg room. I've never used them, but have only ever dared to take adults on short trips in the back. Heated seats are available for the rear passengers. see full Audi A4 / S4 review |
| 2008 | 4dr Sedan 340-horsepower 4.2L V8 6-speed manual AWD |
Depending on how tall your front passengers are, your rear passengers may not have any room to sit. Can fit 4 average sized adults, but it will be tight. see full Audi A4 / S4 review |

The rear seat is adequate, but not large. Child seat fits fine, but my son can kick the back of the front seat. see full Audi A4 / S4 review |
| 2008 | 4dr Sedan 255-horsepower 3.1L V6 6-speed shiftable automatic AWD |
The rear seat is too small for adults on long trips (over an hour). And the rear seat can only hold 2 people even for short trips. see full Audi A4 / S4 review |

| 2007 | 4dr SUV 268-horsepower 3.5L V6 7-speed shiftable automatic AWD |
3rd row seats are big enough and comfortable enough for an adult. 2nd row seats are the best captain chairs I have ever sat in in a car. Glass roof gives additional room appearance. see full Mercedes-Benz R-Class review |

The STANDARD leather seating surfaces on the 2006 front seats - way better feel than artico leather. The adjustment range to get things just right and the head rest. Very cozy. see full Mercedes-Benz R-Class review |

This has to be, by far, the roomiest Mercedes period. Back seat comfort, even in the third row, is unmatched. see full Mercedes-Benz R-Class review |
