Not sure if it has been mentioned.
#1 Please inform your Sales advisor to not drill the front bumper as this is standard procedure during new car delivery. An email is best in order to have proof of the request.

No cutting, welding, drilling 3 min install.
I have this for my mini and the thread patterns are identical.
No Hole Front Plate
The plus side is taking pictures, car shows and whenever you want removing the plate takes 30 seconds. and you just need to replace the cap for a complete stock solution
I can guarantee the threads match up because I own an 07 e92 and a 06 mini cooper. (I have checked)
