I will add my two cents...If the service records are available you want to look for:
Was the Timing belt/water pump changed? (how long ago?
Has the radiator been replaced? If not check the connections for corrosion and plan on doing that. (no too expensive especially if you are a DIY type)
Were the fluids changed regularly?
Was the airbag recall done?
Were the valves adjusted?
If no records are available then you will probably want to have these done at some point and use it as a negotiating tool.
