To the OP:
Out of the two Individual Leathers you mention: Criolla Brown Leather without a doubt and it is also my favourite Individual Leather. Be careful when choosing the external colour with this. You need a contrast. Alpine White, Glacier Silver or Moonstone come to mind. Latter my choice out of these three.
However, colourwise, my favourite is still Coral Red Dakota leather aided by my other favourite: Estoril Blue II. However, Dakota Leather texture has much to be desired.
So top leather out of BMW's meagre list for M-Sport F30s, taking account of colour and texture, is Criolla Brown Leather aided by Moonstone. Expensive combination.
But is it worth it?
