I DID HAVE a 2011 S63 AMG I did not keep calm from 18 km on the odometer .. they said I have to have a test drive at Deliver ... well we opened it up, 110km in first gear on AMG Sport+ ... 3 years of spark plug cylinder 8 cracked under heavy loads and miss-firing cylinder 8 and burning oil like no-ones business ... 2015 S63 AMG followed rules and NO ISSUES ... follow recommendations if you intend to KEEP THE CAR!
no issues on my 2016 M6 Cab or 2007 M6 Cab following recommended break in
