Just about to finish school and have in the neighborhood of $5k to buy a used car - haven't owned a car before so I'd love some tips about what's reliable, economical, comfortable, etc. Thinking maybe a Japanese maker compact - Civic, Sentra, Corolla or the like. All insights appreciated. Thanks!
It sounds like you're on the right track already.
I would recommend a Corolla, Accord, Sentra, or Civic.
I've heard good things about Hyandai as well.
I've had a 2001 Accent for four years now. I've been very happy with it. Hyundais do not hold resale value well so you can get a pretty decent one for a pretty reasonable price. The downside is that you won't get much for it if you trade it in or sell it. I tend to drive cars into the ground so that's not much of a concern.
I'd go with a Civic (or any Honda or Toyota really). Make sure the timing belt has been replaced if it's near 100k miles.
Acura Integra.
