So some bad news, we had a garage fire and lost all three vehicles and my rare Ducati. I'm now in the market to replace my BMW 650i grand coupe M sport with an M6. I'm looking at a 2016 and a 2018 competition package. See the links for the two vehicles and I would love any comments of which one he would get and other recommendations out there

Were there any technology or other major differences between the two years?
