2008 4dr Sedan 162-horsepower 2.4L I4
5-speed shiftable automatic FWD
I researched online and spoke with Optima owners. Kia has come a long way in reliability in the past few years. I was surprised by the level of owner loyalty. People who own Optimas enthusiastically recommend them.
2008 4dr Sedan 162-horsepower 2.4L I4
5-speed manual FWD
Good general reliability, which is backed by an excellent warranty
2007 4dr Sedan 185-horsepower 2.7L V6
5-speed shiftable automatic FWD
I have had zero problems with the car. Trim and everything is just like new.
2005 4dr Sedan 170-horsepower 2.7L V6

Have not had to call roadside service once in three years
2004 4dr Sedan 138-horsepower 2.4L I4
5-speed manual FWD
Have had 0 problems until just recently the clutch pressure plate broke! $800 to fix and not under warranty! Not happy about that.
