To expand on the fluid changes, it is generally best to take the stance that the perious owner "never had to do anything to it other than change the oil". Meaning, the axle and transmission fluids have probably never been changed.
It would hurt to change the brake fluid and power steering fluid as well. Check the condition of the coolant, if it doesn't look bad, check the condition with a dropper type tester to make sure the mix is right and the antifreeze isn't worn out.
Inspect the spark plugs, especially the ones on the intake side, they are a real pain in the butt to get at and change. Inspect the belts and hoses for their condition as well. If I remember correctly, the engine has a timing belt. Look at that too. I believe the mileage interval for changing it is 100,000 miles but there is usually a time limit as well.
Like mentioned above, if nothing pops out on a visual inspection, it will show itself over time as you drive it.
