| 2007 | 4dr Sedan 306-horsepower 3.5L V6 6-speed shiftable automatic RWD |
The seats are very comfortable for the size car. see full Lexus IS review |
| 2006 | 4dr Sedan 204-horsepower 2.5L V6 6-speed shiftable automatic RWD |
The good of the front seat comfort is that the seats are ventilated. They could be stronger and cooler but that is my preference. Why is it that we cant get Audis, BMWs, or Lexus with fabric seats in the US? see full Lexus IS review |

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 |

The front seat headrests are too far back for me. I feel if I use them I am looking at the sky because of their angle. I would prefer some fwd-rev adjustment which i have seen on other cars. see full Lexus IS review |
