Look for P/S leaks. Listen for ticking while idling - if it ticks, it's going to ask you for $ down the road. Check the vents to make sure the air is coming out of the right places. Check the radiator neck for signs of fatigue. Check the suspension (ball joints/tie rod ends/etc). Check the alignment - make sure the back tires do not stick out of far on the road as in /--\ (looking at the rear of the car). And, lastly, check to make sure the antenna works.
btw... they don't exactly sip fuel, so maybe you should check your gas credit card too.
