Hie everyone,was looking to upgrade my car when i saw the Optima k5.Looked great from the outside.So decided to go for a test drive.Unfortunately very disappointing,car felt very underpower and engine was a bit rough and in terms of interior stylishness,it somehow felt cheap.You sit inside and you dont feel like you are in a premium car.You just feel like you are in another Korean car.For normal crusing,this is ok,but for spirited driving,this is definately a big NO.
