| 2013 | 4dr Sedan 328-horsepower 3.7L V6 7-speed shiftable automatic AWD |
I like the seats in this car a lot. The bolsters feel well placed and keep you from moving around too much when cornering with enthusiasm, and they're comfortable to sit in overall. see full Infiniti G 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 |
