It's all about balance / compromise.
Agreed that the livery mistake on the EGV's is a shame, and maybe it could have been caught earlier.
At the same time, it hasn't stopped me splurging all over them. Yes, phrasing, @JasonB.
Anybody remember @connollystn talking about how terrible the Murphy Models 201 is because of where a socket on the bumper should have been, but wasn't?
It was a compromise that we have to accept in the price vs. reality debate.
Also, on realism, I'm sure a TLC scales up ro something like one and a half metres. Another compromise we accept.
The bogies on the Mk2D's, from chatting with forum friends, seem to be an upgrade on previous iterations. As does the bogie mounting point on the body. Both changes would have meant new toolings, yet the price is only something like €5 more than the last ones?
I'm sure that some genius will run decals for the EGV sides, and solve the problem. Whethere they should or shouldn't have to is another thing, but I'm sure we'll have a solution.
The mistakes on the 141's / 181's at the Raheny show were probably as @JasonB said somewhere, just bodies from the older runs used to showcase the new liveries.
