Hi Smaug,
as has been said, the rest of the problems have been largely sorted. Things to look out for:
1. Exhausts cracking: but you should have the new ones, and if they are OK so far then you probably have!
2. "Bevel Box", again this seems to be down to correct and careful lubrication with the right grade of oil. Even so probably worth changing the oil every 1500km for the first year...and talk to your dealer to see what MMC recommend.
3. Final drive pulley wear, some do some don't. Just watch it.
I've got a Roadster: it is utterly reliable (unless I do something stupid, it has been known) and I'm now thinking about a new M3W next year as a second car.
Oh, what colour and details? do post a photo!
