I mean why not get a used Corolla for something like 4k? Maybe 5k? I don't know how much you are spending, but an old Toyota will be reliable past 200 000 miles, easy and cheap to repair, and you can find one that was a one owner car, ideally a grandma or priest.
You might be interested in the Suzuki Mirage as well.
If you are stressed about reliability, don't worry. You need to do regular maintenance (oils, fluids, filters, tires) and you'll stay on the road longer than brand new cars. I had a Chevrolet Aveo that had the radiator blow up while leaving the dealer!
