I assume it is a 1st gen aveo for that kind of miles, not a bad car overall, but the big thing to check is the timing belt, at 120k or so it may very well need one if it has not been changed in the last 40-60k miles, if I was in your position, I would look at some other options, but if you can get the aveo at a good price/well maintained then you can't go wrong.
