You should seriously consider a new car.
I recently bought my first new car, and can offer some help if you want.
The next couple of months will be the best time in your lifetime to purchase a new car, simply because there are so many unsold cars out there, dealerships are DESPERATE to sell. You will get a great deal, if you manage your purchase carefully. Get a quote, and don’t be afraid to ask for more, no matter what kind of “no haggle” policy they might say they have.
New cars make sense from a couple of standpoints:
One is that your costs are very predictable. Buy and older car and you have much more variability in terms of not knowing when a repair bill will creep up on you.
New cars make sense if you intend on holding them for 5+ years. 7-10 would be ideal, longer if the car has proven reliable.
With this in mind, choose something small and fuel efficient, with a good safety rating.
From there, go on to find one that is fuel efficient. Gas is fairly cheap now, but WILL get more expensive, sooner than most think. Going for something fuel efficient now is a choice you will not regret.
Start with either the fuel economy:

or the safety rating and then to fuel economy:

The corolla or civic is generally a good choice, but don’t discount a good Ford Focus, which would end up being a VERY cheap option, and is pretty fairly equivalent to either the corolla or civic, don’t let anyone tell you otherwise.
This is all I have time for at present, but check your mailbox.
