I know nothing about these cars and have been asked to go look at one for my sister to see if she should buy it. So being active on other car fourms I figured the best way to get the information I need is to ask the people who know these cars inside and out.

So what are the common problems on these cars that almost always need to be addressed when buying one?
Where should I be looking for signs and symptoms?
Whats the standard tune up on one of these with 120k miles on it I figured automaticlly the basics of all cars all fluids changed, new plugs and wires, brakes, the whole works.

Your knowlage is much appreciated and sorry If I posted this in the wrong area lol
