Last November, I moved from a 16 Sorento to a new SX Seltos, and definitely haven't regretted it. Gas mileage is good, but I can't give you specific numbers. It has a stiff suspension, but having less than 500 miles on mine, no idea about the life of the shocks. Road noise is so-so, however. I'm planning to put sound deadening mats in mine to reduce that greatly. Since this is easily fixed with a little effort and a few hundred dollars, I wouldn't consider it a reason NOT to buy one, though. I've done research into methods and products, so if you decide to buy, I can give you some links.'
I'm very very happy with my Seltos.
