I test drove a Kia Rio wagon with my wife.
The interior was kinda' cheap.
The overall car was O.K., assuming you are comfortable not paying much and not getting much car.
My biggest complaint was that the car is
D O G
S L O WWWWWWWWWWWWWWW
My wife was driving along at 35, decided to test it, floored the gas, it downshifted promptly, and we proceeded to tool along at about the same speed we were at when she floored it. The engine buzzed like a bumblebee that just came home from work early to find you in bed with its queen and the thing s l o w l y made it up to 40.
If you can't stand a car that accelerates like a pre-WW2 tractor trailer, don't bother test-driving it.
I seem to recall that its crash rating was ABYSMAL, too.
Nonetheless, if it was the only car I could afford, it would get me to work and allow me to continue feeding my family, so I'd drive it if it came down to it. Maybe if I was younger and made less than I do now, it would be worth considering.
