Panel Alignment-Is it Fair to "Cheat"?

This reminds me of when I was fitting the fenders to my Duster. In order for the fender to line up with the hood the gap at the door was to wide. I thought the cowl was bent back so I was going to pull it. The tape measure was laying there and my son about 10 yrs old was measuring everything in the garage.

He came over to me and said "Dad do you know that the door on the other side is longer than this one". I told him that he was probably measuring it at an angle. He came back over and said no Dad this door is 2 little lines longer. I got up and measured them and he was right The left door was 1/8 to 3/16 longer. My car always had wider gaps on the right side that was the way it was built.
