I traded my Infiniti G37x (which I loved) for the Sportage primarily because the Infiniti was too fast for my soon-to-be-driving son. The gas mileage is not as good as I expected.
In the first few hundred miles (I have 2500 now), I was getting about 25 mpg combined.
That has since been averaging about 20-21 which is still better than the G37x.
As for the price, I don't think there's a better value for what you get: AWD, Uvo system, nice cloth seats, backup camera.
Drove the Mitsu Outlander Sport and Tucson, but the Mitsu 140hp was anemic and like the looks of Sportage better than Tuscon. Also, the Sportage's ride is not stiff, it's downright harsh, but I knew that going in.
