Exactly Dave.
It can, and never will be, completely accurate (almost anything in 1:72 is automatically out of scale, due to the tiny nature of the parts!), but we are creating an illusion, trying to make it 'look' realistic, without actually being so.
I personally will be happy if it 'looks right' or atleast 'semi-right', but I need to change a couple of things with this one for that yet.
