2006 Kia Optima Seat Room and Comfort: Pros
Year	Body/Powertrain	Comment
2007	4dr Sedan 161-horsepower 2.4L I4 5-speed shiftable automatic FWD	Spacious enough to allow my 84 year old mother to get in and out without injuring herself! see full Kia Optima review
2007	4dr Sedan 161-horsepower 2.4L I4 5-speed shiftable automatic FWD	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
