Should there be a law

May I ask why you didn't stick with it?
The hurt feelings, you will have that to a degree with any mods. Even when all Mopar.
Non body color under hood paint for example will ruffle many feathers in the Mopar world.
I only have very modified cars myself. For both reasons of a purchase price I could afford and personal preference. Never been afraid to cut into one of my Mopars as they were unloved derelicts when I obtained them.
I do avoid the most common annoyances while building my cars and agree with the annoyed on most issues but not all. Many different levels of tolerance to be found in this social group.
