Why do you assume that everything is personal?
You think this doesn't matter because you personally don't care.
You think I'm complaining because I personally do care.
Try to look at this in a general way. This kit will sell hundreds of copies. Perhaps many dozens of people will buy it without reading reviews, they will trust what the webshop says. And there are webshops already saying "full interior" and they're saying it because they see it in reviews, they're not panzer experts.
Many of those buyers will be disappointed by what they get.
What would you tell them, Matt?
"I can deal with it, and so should you"
"Call an attorney"
Your attitude seems to be "Screw those guys, I'm OK"
