Dave,
Assuming this isn't a convertible, the factory height for your car is 53.1 inches. Ideally, it would sit level, across the rocker panel bottom. The way to measure it would be to make sure your tires are inflated correctly, on a level surface, all the non-factory stuff removed (extra tools, golf clubs, etc.) with a full tank of gas.
Then measure the ends of both rocker panels. That should tell you which corner(s) are sagging.
Somebody may have an easier way, but that's how I've done it before.
Kurt
