25. Cars are unfortunately also a necessity outside urban core areas in the USA. I'd have to drive nearly 10 miles to find non-school bus service that runs at all that isn't exclusively for senior citizens and disabled people, and even then, it only goes to the core from 5 AM to 6 PM (buses head out from the core starting at noon from the core and run until 10 PM) unless it's State Fair time.
Anyway, look at getting anything in the sub-compact to mid-size sedan range. Bigger than that would give you more horsepower and space, but it'd consume more fuel and be out of your price range for anything with decent fuel economy. Toyota and Honda have well-earned reliability reputations, but you'd be paying a premium for used. You can often find better deals on something like a used Civic at a non-Honda brand name dealer (like a Ford or Toyota dealer). Same logic applies to other models from other manufacturers (ie - finding a deal on a Corolla at a Chevy or Honda dealer). Larger dealers have more leeway in what discounts they can give you, typically, if they can give you any. /r/whatcarshouldibuy should be a good resource for you.
Thread title is just to make people aware that SAO II is running on Toonami now.
