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 |

After driving the Optima for five days straight for 10+ hours per day, other than the occasional stop, on a road trip, not one time did I get a sore back or thighs. see full Kia Optima review |
