In Germany/most of Europe the Alcantara seats come as standard in an M sport/M340i (you can check out the German BMW website to see how it looks). If you go for an Individual Paint (except for P1 options like Dravit grey or Tanzanite blue) the car will be produced in Munich, and I think you should be able to request the standard alcantara seats relatively inexpensive or maybe even free (compared to full Individual leather, which is like $5k). Nonetheless, it will be a special order.

A full Individual Manufaktur interior (you can basically specifiy the color and material of every single panel and stitching individually) is about $15k on an F80 M3 to give you a rough estimate of what you can expect to pay if you go that route.

Carbon fibre on the outside is port/dealer installed M Performance parts which are available in the US, just ask your dealer. Or go with third party options which can be cheaper or can have a different design.
