Other cars with full manufacturer maintenance plans will be comparable. BMW's was, as a rule of thumb, R20k+ per year a good few years ago; it's probably in the same ballpark by now. I don't think the value proposition is particularly compelling.
I extended my BMW motor plan by a year in December last year for R12,000. Time only, as the car was still a good 20,000km under the 100,000km limit. It escalates pretty quickly if you want to extend distance though.
Anyway, sold it, driving Subaru now and the salesman himself told me not to bother with getting an extended motor plan
