Based on how little money you have to spend on a used car, you certainly should not rule out the Fit. In fact, if I was doing a blind purchase, I'd pick the Fit over the Vibe any day given it is a tough car to destroy. The long term reliability of the first and second generation Fit is arguably the best in auto production history. So in your case, with little money to spend and even less to spend on repairs and unforeseen "pass me down" problems from the previous owner, I would strongly suggest you find a high mileage first or second generation Fit, even one that has a re-branded title due to a minor accident. Buy it from an original owner or at least someone who you can look in the eye and ask tough questions about the car's maintenance history. Don't pigeon hole yourself into a Corolla/Vibe/Matrix especially given some some of the stupid issues resulting from less than stellar Toyota parts suppliers over the past 10 years. With little money, shop for the best, one with an impeccable long term history: Jazz/Fit.
Live it up: There will be plenty of time to be old when you die.
