If you didn't build the car...

The sad part of calling out the current owner of a car regarding the original build is that it will cause the initiation of a tale of how much they had to "fix" "poor workmanship" and other malady's, real or imagined that somehow works to justify their opinions. This goes on to generate more bad blood in the hobby.
The finger pointing and fussing gets to the point where car events have more drama than quiting bees.
