Honda civic for a sedan, but consider one of the micro wagon versions of the civic. Or even the honda fit.
They are pricey for used cars but that's because they hold their value, and THAT is because they run darn near forever. I have a 2008 civic with the navigation system and it's a great car, economical and versatile. The hatchback or small wagon or whatever they call them now versions are even better since you can put bigger boxes in the trunk. If you think you will ever take the car on trips, the honda navigation system is in my opinion the most user friendly one on the market. I've tried several, and the honda nav system is very good and easy to use, even when driving.
Or even a base model civic... They are generally reliable and economical, with tons of nice features like optional split rear folding seatbacks (worth looking for if you get one used), and various other little nice to have features. My only gripe about the civic is that 4-wheel disc brakes were not even an option except on the top of the line most expensive model... That sort of drove my decision to spring for the navigation system too, and we haven't regretted spending the extra money since the nav system has bailed us out of bad trouble a few times.
So... civic or fit, either sedan or hatch/wagon models.
I saw the recommendation for the toyota corolla, but make sure you test drive one. I have fairly short legs so I'm that guy who always has to pull the seat forward, but in every toyota I've ever driven including a corolla my wife owned, the pedals were waaaay too close to the driver. In order to have a comfortable position for my feet/legs, I had to have the seat far enough back that my arms were stretched waaay out straight to get to the steering wheel even with the seat fully upright. Maybe they're better now but even a 2010 sienna I test drove had the same problem, pedals too close to the driver, so I couldn't find a comfortable driving position. The hondas I've driven, including my civic and odyssey, both feel much better and feel fine to my wife as well. So test drive it to see if you fit in the car first, and pay attention to how far you have to reach for the steering wheel after adjusting the seat position for your feet and the pedals. If you have to stretch or lean your upper back off of the seat to reach the top of the steering wheel after adjusting the seat for the leg/feet position like I had to do with the toyotas I test drove, then you might want to try another car.
