Wrenneire - thanks very much for these photos which answers the question with great clarity for me anyway.
As someone who was planning on buying 31 of these babies, I now have to go off and have a serious think about this, as in my mind, these coaches should be a close match or at least very similar to the top 141/181 and 071 in the photo. The colour of these coaches now looks like a half way point between the colour of the IR/IE livery portrayed on previous MM locos rather than Supertrain.
To say I am disappointed is an understatement, as personally, If I am to continue with my plans for a CIE era layout, I would have to now add in the cost of a full respray to each coach, which at this point, I am unsure is a financially viable option for me anyway.
I am sure that there will be many modellers as happy as a pig in poop with these coaches, but personally, I don't know how MM could get it so wrong this time around. There have been livery issues on previous MM products that could be easily fixed and that I have happily lived with, but certainly none that required a full respray. Disappointed big time.
