Firstly nice colour choice MCB is a great colour on this car, The interior colour however is not to my taste , but each to there own.
TOW-BAR!!!!! what on earth are you going tow? with an M5.
My running in procedure was much different than yours, I got everything HOT and then for the first 40 miles gave it the beans too 5.5K.
Result NO Oil used @ 4900 miles.
Car can spin rears even in 3rd/4th gears, goes like a rocket.
I have fitted 20" winter wheels with Michelin Alpin's and the car in these conditions is
rock solid a real pleasure to drive.
I hope you enjoy the car for many years to come.
PS) Mine is not CP, I could not find any use /advantage to it in my driving.
