wear and tear in the bodies and subframes over a long time. from new about 3mm higher one side, I have noticed about 8mm variation in height as I check before I replace rusted guards and front apron. Also the subframe needs to be held down one side and jack up the other. I used to use 3 gunsight gauges which go across the body in 3 places. Now with a flat steel bed like the Caroliner it is easy to measure vertical datums ,lengths and width. Problem is easy to fix, My CS is within 1mm tolerance new cars are plus or minus 1 or 2 mm tolerance .Maybe some are perfect I have measured different makes of cars.
Interesting...with all the other variables that effect handling like sub-frame and suspension alignment and driver weight etc must be good to know you have at least started with a straight body
