Congrats on the car.
I also came from the same car, F80 M3.
This was my thread when I got my M3

Before the M3, I had an M6 with the same engine, then went to the M3 and the S55 engine and now back to the X5M.
Power is deceiving in this big beast. It sounds better at startup, but somehow I miss the rattly sound but not the startup of the M3. Also, the toss-ability of the M3 was nice to have, however, this car sticks given its weight. I guess BMW played with Physics.
I just needed a bigger car and this is why I got the X5M.
I also got the Donington grey but with Argon Grey. Will post pics later.
Agree on the interior quality and Alcantara roof plus B&O.
I just need to get downpipes and a tune. My M3 had both and that was just fantastic.
Will do some V BOX runs later.
