335i Motorplan Extension Cost OMFG!

So,

My car should be out of motorplan by November this year.
It's an '08 335i Sedan (Manual) with 87 000 on the clock.

I logged onto BMW owner's circle to see possible MP extension costs.
Needless to say...

I see they removed the "time" option, you can only do it by KM.
Just as a matter of interest, this related to a cost of R2.78 per KM.
