it also depends on the following things: auto or manual transmission, has a/c or not, has cd player or not, power everything or not, has sunroof or not,etc. so tell us the detailed infomation and we can give an assesment.
the mileage is not too high actually if a car is 6 or 7 years old.
if the car runs well, i mean, the engine, transmission, brakes, then you can buy it at $5000-5500 which was told by my friend who works in a garage. just my opinion
