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 |

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 |
| 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 |

Yeah, the back is small but still big enough to handle for the poor rear seat passengers. see full Lexus IS review |
