2013 M3 questions

I am going to purchase my third BMW soon. I have decided to dive into the deep end and go for the 2013 M3.

This is my first post on Bimmer Forum so I appreciate your patience.

Questions: 1. My other Bmw's have had run flats. I am getting the competition package and there are no run flats. How well do the tires hold up? I have never had a flat with the run flats. I am concerned about not having a spare.

2. I am looking at European pickup and I understand that the 2013 M3 will be built until October of 2013. I am planning on a mid July pick up in Munich. Is this information accurate?

3. I have always had a manual. I love my 135 Coupe and I just cannot imagine an automatic transmission. Thoughts and feedback on manual vs the double clutch 7 speed.

4.I also plan on sticking with the carbon fiber roof and not going with a moon roof. Feedback on this?
5. Any other information that is important for me to know right now.
Thanks for your feedback. I am glad there is a forum like this for my questions.
