I purchased the vehicle used, and made the choice between the Rondo and a Chevy Malibu Maxx. For the price, the Kia was more, but the mileage, warranty, and overall vehicle was a better fit for my family, and I wouldn't turn back now.
The V6 and 5 speed auto work together greatly, and put down passing power very well. I have never had to question if the car will fall short of necessary power.
I average 20MPG in mix use driving, which is understandable for a small V6 on a large size wagon, plus I have a heavy foot.
Ample cargo areas and space, the under floor cargo in the hatch area is just plain awesome and handy for things that may spill (had to test this during Thanksgiving time with a few food dishes). The overall seating area though is quite impressive, though smallish from the outside, sitting inside almost makes you feel like you're in a much larger car with how much head room and seating space there is. 4 grown adults can fit in this car very comfortably no problems.
The ride is great and composed for a car in this class/price range. You feel the road well enough, but not every pebble.
