Anyone who has owned a Mustang converatble wll undestand the issues with rear seats in this car. I keep the seat backs down and drive as a two seater. Also Some may find not enough storage bins and cup holders are a tad back for those of us who have shorter legs. But not a deal breaker. see full Infiniti EX review |

The back seat is small, not a problem for my wife and I, it works just fine for our limited use. see full Infiniti EX review |

In agreement with 99% of all other reviews...back seat is a little small but it isn't to say that you cannot sit back there. Taller people may be a little cramped with head and legroom depending on how far back the front seat is positioned see full Infiniti EX review |
