Mileage is less important than how the vehicle was maintained. My daily driver has almost 800,000 miles on it, only one engine rebuild. Runs perfectly and looks great.

Maintenance is much more important than the mileage. If a car is well maintained then it'll be okay even after doing 2,00,000+ miles. But if a car is ill maintained it'll get totaled after 20000 miles. So before buying the car take a mechanic to check the car out. Ask the owner how often he took it for servicing. Notice the little details on the car. You'll know a well maintained car when you see one.
