I am looking for a used car and came across the 08 Kia Rio. KBB values it at around $4500-$5000. The car I'm looking at has 63k miles and a clean title. She is the only owner, and says she hasn't experienced any problems. I've read a lot of reviews, and seen the safety ratings but there are so many out there, I don't know what to think. I don't know how to filter through who is just complaining for the sake of complaining and who actually has legitimate concerns. Please help.
