Maybe other batches will be improved. AFAIK there were more faults with the functioning of the model that cannot be compromised because it is a model that is supposed to work. I hope further batches will have these issues sorted out.
The model looks perfectly fine to me, having wipers facing the same direction is a possibility in the real world, the dimples on the roof are again prototypical and I cannot be bothered about small latches on a battery box!
The model looks superb to be, I've heard about a lot of operational faults and hence not bought one. I'm waiting for a EWS livery one
