2007 | 4dr Sedan 325-horsepower 4.5L V8 5-speed shiftable automatic RWD |
Very comfy, yet generally supportive. Highly adjustable with two memory options. Cooled and heated seats are wonderful. see full Infiniti M review |

Most front leg room compared to similar vehicles at the time. Even rear leg room fair. First car I owned with rear view camera still working well with great color and resolution. see full Infiniti M review |
