Mine came without but after my dealer created a lot of fuss, a pair appeared and one was fitted, the other handed to me.
My personal opinion is that after initial deliveries, the programme lost momentum and people moved on. Remember this was a NMGB idea only - didn't apply anywhere else in the world (as far as I know). the GT4 branding was only used intermittently worldwide - it was, after all the "35th Anniversary Edition" in Japan and the US....
I'm fairly convinced the 176 number may never have been reached...... Certainly Black ones are rare (or less noticed!!) and there are supposed to be 100 of them....
Still love my Ultra Yellow though!!
