When you had a Pinto, the frames of American cars were slapped together with
hammers and approximate spot-welds and nothing really matched. The doors
didn't fit right, the hood seams were never nice and straight. Because
of that, a lot of precision things like headlight positions required
adjustment because they were relative to a frame and body that were not
straight to begin with.

Now that car bodies and frames are built to rather higher degree of
precision, many adjustments that were once critical are no longer necessary.
