 I bought this car with 6 miles on it and commute 80 miles per day.  Almost 4 years and 78k later, I am still in love.  The only dislikes naturally go along with the Kia brand...road noise.  Once you get past that, this car drives like a much more expensive one (as long as you don't think you need to accelerate like a race car driver) and is a great buy.  I get an average of 36-38+ with a combination of highway/city miles AND adding the spare time (most new vehs removed this so increase gas mileage - it doesn't have a big enough impact to be without it on this model!)  Only normal maintenance has been performed and I run conventional oil in it....looking forward to seeing how many miles I can get out of my little girl!
