Not Ranked
I have ERA #003 and do not have these alignment problems.
Everything sits level and square (at least to my calibrated eye).
That being said, these are still hand built cars and each one will vary.
I used to be an engineer working for McDonnell Douglas on their MD80 final assembly area. The assembly methods of aircraft have changed little 70 years. They are mostly hand built.
If my memory serves, the tolerance on the overall length of an MD80 was 147 ft...... +/- 2 ft.
