I've owned Cadillacs, Hondas, Toyotas, and Nissans. I absolutely love this car. It rides as smooth and quiet as a Cadillac, but came with more great options than a Caddy at twice the price. I've had to have the computer tweaked once. Comfort is an absolute plus. I can drive for 5 hours and not be remotely tired (and I'm 60). The Infinity sound system is very good, but, yes, a Bose is better. The warranty program is excellent and Kia certainly stands behind their product. Handling could be a tad better, but you quickly get the feel of it. I have to admit, I took KIA off the trunk and changed the wheel covers, which has generated many questions as to what kind of car is it. I love it.
Seats are VERY COMFORTABLE! A very smooth ride. Good sound system. Excellent heating/cooling system. Bought it for features and comfort and got both in spades.
