As an option, you can get a new compact or a midsize sedan of Korean origin. This summer they were selling the Elantra for around 12k, brand new, but with no AC. Yes, 12k+tax for a brand new midsize sedan. Later there was the Elantra GT, auto, with AC, being offered for 15k+tax cash. 2014 M.Y. cars can be found still with considerable cash discounts (look at Kia as well). If you need more room, there maybe '14 Sonatas left (last year before refresh), must be hugely discounted if you can find one.
BTW, I had a 2009 4 cyl Sonata that was very fuel efficient, and not one thing broke on it either.
