Sold my 2017 M3 and just bought a CPO 2018 M550i in Rhodonite Silver.
Bought it with the 20" 668M wheels, which I will be putting up for sale on the forum soon. I put a new set of 19" 647M wheels on it after seeing a few pictures of them on the G30 5 Series online. These are 7 Series wheels, 8.5" front and 9.5" rear.
The car has the M Performance side skirts, carbon fiber mirror caps and carbon fiber rear spoiler. I am almost done replacing all the Cerium Gray trim pieces with black trim.
Here's my previous car, a 2017 M3.
