M235i is available for rent now at Welt in the BMW on Demand program for 45 euro/hour (only 3 hours charged gets you full 9am to 5pm or 5pm to 9 am).
If you want to follow a strict break in but still want the opportunity to really beat up on one of these, that's not a bad deal.
Cancellation is no charge so I have an M6 and an M235i booked for the night before I do ED. Now to figure out which one I want to abuse more.
I did an M3 with them a few years back and it was a blast as I punished that car throughout Germany and the Swiss Alps.
