The black pack gives you darkened headlights too. It's still a silly price though! I mean they're the exact same units, just with darker reflectors! I'm not sure if it is a mistake, it's hard to see how it can be justified. Note, its down as 1600 euro on the Irish configurator!
Yes, seems you are forced to select DCC now with any of the 19's options. I think you should spec DCC anyway, it's a must have for me, but for sure, it does make the wheel upgrade "seem" expensive.
