A two week production delay on my week 11 build compounded with Easter shutdown left my cars arrival three weeks later than expected.
From what I can see M3W's with standard or near standard spec are being churned out though, but surmise any with some/most of the new for 2016 options may be delayed due to lack of availability. I know for a fact the rear mudguard is not available yet, despite having had one on order since before build started.
