It sounds like you're on the right track. Get a pre-purchase inspection so you'll know if there are any major problems with the car.
Once you get past a certain point (seems to be like 5-7 years on my BMW's) you have to replace more than just "wear items". The main parts that seem to have experiation dates are usually made of rubber, like gaskets and seals and stuff. They just wear out in the weather.
