I bought this Kia Optima several years ago used and only owned it for 8 months.  It was only 3 years old and already falling apart.  Only 2 months after I bought it parts started going bad on it.  First the water pump bearings went bad and then the radiator leaked and then the started misfiring.  I maintained regular maintenance through the dealership, but nobody could identify the cause of some of these problems.  Not to mention that the V6 got horrible mileage.  The inside of the car was nothing to write home about.  Inside and out this car didn't last.
