More padding, slightly larger than e46 sport seats, fully adjustable side bolsters and the Dakota leather seems thicker and softer than the e-46 leather. see full BMW 3-Series review |

With a 6-foot driver, rear seat room is barely adequate for adults, for short trips. This is typical for this car segment, though. see full BMW 3-Series review |
| 2009 | 0 | Not much room in rear see if driver is 6 feet tall see full BMW 3-Series review |

ride is very jiggly, can feel every imperfection in the road. I think the tires may be very poor for this car. see full BMW 3-Series review |

It has a back seat, but unless it is a short trip it is very tight for adults. see full BMW 3-Series review |

| 2011 | 4dr Sedan 420-horsepower 5.6L V8 7-speed shiftable automatic AWD |
Very comfortable up front. see full Infiniti M review |
| 2011 | 4dr Sedan 330-horsepower 3.7L V6 7-speed shiftable automatic AWD |
The footwells are very narrow for a car of this size. This is a side-effect of it being RWD. The "dead" pedal seems to be in the wrong spot, at least for me; it's too far to the right. On the plus side the air conditioned seats are great. It is possible to drive around in 90 degree weather wearing shorts, with the windows down, and feel comfortable. see full Infiniti M review |
| 2011 | 4dr Sedan 330-horsepower 3.7L V6 7-speed shiftable automatic RWD |
Very envelopped and comfortable seat, have better padding, and seating posture is better than most of the luxry cars I tried. see full Infiniti M review |

The fronts seats need more bolstering. The BMW 5 series has much, much better seats. If I could change one thing about the car, it would be the seats. Anyone considering this car should sit in the seat at least 30 minutes before making a purchase decision. see full Infiniti M review |
