@Edwin:
I had EDC(sort of adaptive drive more or less) on my ex E90 M3, and never used it actually.
That BMW guy is a perfect salesperson because the adaptive drive option is a bit more expensive. Or was it Andy Priaulx/Jorg Müller
Anyway, the stance of an M-suspension equipped F10 is a bit better as well, it stands 1cm lower fwiw.
BTW when is eta for your 535d?
Cheers
Robin
