ford mondeo ghia mileage high good price any reason shouldnt buy?

ford mondeo ghia x year 2000. high mileage over 100000 should that put me off or if the price is reflective what do i need to think about looking out for? I know there is no warranty after 100000 miles so the car is buy as seen. Also do you know how often time belt needs to be changed anyone? Thankyou
