With that many miles, I usually tell people to put it on a lift and do a good assessment of corrosion. Even with a mild environment and being garaged, there are spots that have a tendency to corrode. The inner and out rocker panels will corrode from the inside out. They will look fine, but one day you will push on the paint with your finger and find no metal behind the paint. The lower radiator support where it attaches to the frame will holds water and rusts out. The frame cross members above and behind the transmission can also hold water. Finally, the spot/pinch weld above and behind the rear tires. If they start to corrode, they will mushroom, letting water in and causing more corrosion.
Mechanically, consider the struts, suspension parts, steering linkage. Ball joints, rubber, and bushings. These are 300-400K engines. I did a complete teardown and rebuild at 250K. I can tell you that with regular oil changes the internals were good. I check the crank for wear to see if I needed oversized bearings and there was less than .0005 wear. The one lubrication problem that seems common is the cam journals on the passenger side. It is at the end of the chain and if the oil path gets block, it doesn't get good lubrication. My cams were worn out of limits and needed to be replaced.
