| 2012 Audi A4 / S4 Seat Room and Comfort: Pros | ||
| Year | Body/Powertrain | Comment |
| 2012 | 4dr Sedan supercharged 333hp 3.0L V6 7-speed automated manual AWD |
Without question, the most comfortable car for long road trips that I've ever owned. Our family of four took a road trip of ~2000 miles, longest single-day drive was 11 hours, and never felt any fatigue or discomfort from the seating. Seats are firm and supportive but not harsh or uncomfortable. see full Audi A4 / S4 review |

waste of space, no good for seating, so should have been made for storage see full Ford Mustang review |

There is very little rear leg room, but this car isn't meant to be a people carrier. It is nice that there are rear seats, but anyone that is not a small child will have a hard time sitting in the back. see full Ford Mustang review |

While our present government may blow off the standards & principles of the Geneva Convention, I still find them worthy enough to abide. Mustang rear seats are in clear violation. see full Ford Mustang review |
