Want a reliable used card, budget 6-7k.

Hello, I'm a 21 year old dude entering his last year of college. I expect to have a pretty good salary coming in soon after I graduate, given the career outlook of people who have taken similar paths. I'm mostly looking for a good, modestly cheap, reliable car to last me for a couple years. Something I could theoretically sell in a couple years when I am hopefully able to upgrade. Something with low insurance estimates would be great as well. I've mostly been looking at Honda Civics so far in the 2002-2009 year range. Any suggestions would be greatly appreciated.
