Year | Body/Powertrain | Comment |
2010 | 4dr Sedan 204-horsepower 2.5L V6 6-speed shiftable automatic AWD |
Lousey seats: uncomfortable and build is cheap and not conforming to human posture. But, seems last several years most cars have lousey, cheap and uncomfortable seats. see full Lexus IS review |

Legroom felt narrow for passenger over tranny tunnel. see full Lexus IS review |
2009 | 4dr Sedan 204-horsepower 2.5L V6 6-speed shiftable automatic AWD |
Cramped rear seat. Minimal knee and leg room when there is a front driver/passenger. Minimal room for the toddler when sitting in a car seat. Seats 2 small kids at best. see full Lexus IS review |

Yeah, the back is small but still big enough to handle for the poor rear seat passengers. see full Lexus IS review |
2009 | 4dr Sedan 306-horsepower 3.5L V6 6-speed shiftable automatic RWD |
This is a small car. Interior seating is comfortable but tight. Unless the driver is very short, forget about the back seat. see full Lexus IS review |

Don't buy this car if you ever plan on carrying four adults. see full Lexus IS review |
2008 | 4dr Sedan 204-horsepower 2.5L V6 6-speed shiftable automatic AWD |
The rear seats are very comfortable, but TINY. see full Lexus IS review |
2008 | 4dr Sedan 306-horsepower 3.5L V6 6-speed shiftable automatic RWD |
The rear seat really is too small for adults. The front seats have to be moved forward for adults to sit in the back. see full Lexus IS review |
2008 | 4dr Sedan 416-horsepower 5.0L V8 8-speed shiftable automatic RWD |
Not enough rear legroom. see full Lexus IS review |

Small rear seat. More like a coupe with 4 doors. see full Lexus IS review |

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 |

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 |
