Did a ton of research as I was a little hesitant about buying a Kia. My first choice was the Honda CR-V and then the Ford Escape. The Sportage puts both of those to shame, especially the Escape. There is no comparison on the interior or the ride. Once I test drove the Sportage I knew it was the right SUV for me. I love it and can't be happier.
Everything. Fun to drive, very smooth ride.
Only improvement would be that the doors automatically lock when the car starts or you put it in drive.
