What are some good, cheap cars?

for a 16 year old girl, turning 17 soon, I want a car that's good on gas, but is cheap (under 5000) and cute. Three cars I have been looking at are Toyota Echo, Chevrolet Aveo, and Kia Rio RS. Used cars are what I'm looking at, and I would love if someone had some suggestions for more cute cars, or any input on the three above. I KNOW that cute isn't what i should be looking for, but i really want a cute car ;) (and this is in style, because I would like some Girl's points of views so don't complain about it being in the wrong category)
