Thats an M shiftknob and m steering wheel.
Seperately purchaced or option ticked parts.
It's basically ordering a z3 and pay for fitting an z3m steering wheel.
So its something you've asked$paid for. Indeed bmw has been doing that for a long time.
So its not really fitting m badges, but equipping the car with parts meant for an m (but usually they were listed in the brochure, often even before the m version was available. In the e30's days they had a whole line of parts called 'M technic' I think, but as far as parts bolted on the outside I think those never were fitted with m badges like they are now)

I tought you had like a base model where bmw just put m badges on (so on the outside at the type badge)
