A lot depends on what we've using our cars for.
I'm not 'contest quality' modeler, 'layout quality' at best. My cars are made to operate on my layout. If I had several members of this group in my ops team I would take their criticism because my models represent the best I could do at the time. Sure, I'd upgrade if information surfaced. But, I don't have any of you guys regularly at my house. The guys that show up don't know and or don't care that much about accuracy. I still feel the need to do the best I can, others are happy with 'close'.
