The dead battery may be a sign of things to come. I never trust used cars that just got a new battery.
Remember to check front CV boots and rear springs should have been replaced by now.
If you buy it replace the fuel and air filters, plugs, oil (unless you know what kind it has). Expect window regulators to fail eventually, not a big deal. Coolant system is a bigger deal.
If it idles and drives nice, has new brakes, needs tires and probably control arms and bushings, around 10K seems like a fair price.
