 Our 2005 Optima is most impressive in terms of value versus performance/confidence in driving. It is quite comfortable driving with the manual adjustable lumbar and seat adjustments. We have a 5 speed with overdrive and, although it doesn't have the power I am used to, the mileage we get more the compensates for the lack in overtaking other vehicles on the open road. Now, don't get me wrong we cruise at 74 mph at a little of 3,000 RPMs very comfortably and experience much less road noise and vibration than the Corolla we've rented a number of times with intent to purchase. My wife and I realize the South Korean automakers are serious contenders in the market and our decision was sound.
