YearBody/PowertrainComment
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
