Smaller than the Maxima. Third person would be uncomfortable, less knee room. The plastic trough behind the front seat is too low. see full Infiniti G review |

The rear seat is basically a storage area. No one can sit back there! But its really no different than the rear of any convertible. (like my Mercedes Benz CLK350) see full Infiniti G review |

Seats in back are cramped. Once the kids hit teenage years they are not going to be happy back there for long rides. see full Infiniti G review |

Seems smaller than the G35, no rear reclining seats anymore and the headrests stick up a bit more than the old car. see full Infiniti G review |
