They probably did catch it, then measured it, then decided it was in spec. My left side also sags by about 1/2" (1/2" in the back and a hair less in the front). I told them when I got the alignment to level it out as well. When I picked it up they told me they didn't level it because it was all within spec.

Some kind specs that dictate a 1/2" difference in elevation on the sides of the vehicle. <img src="/forums/images/graemlins/barf.gif" alt="" />
