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 |

Very fast, high torque throughout the range. You cannot shift as well as this 7 speed auto, so manual mode is all but irrelevant. see full Infiniti G review |

very fast, but then again, upgrading from a 1999 civic....anything is fast. see full Infiniti G review |

Smooth as silk power and loads of it--more than anyone really needs for daily driving and more than enough to always bring a smile to your face. see full Infiniti G review |

I compared the G37x to the BMW 325 xi. I chose the G37 x because it had better throttle lag, and more precise road feel, although a somewhat rougher ride. I also believe that the repair and maintenance costs of the Infinity may be less than the BMW for comparable repairs or maintenance items. see full Infiniti G review |
