So with some extra time on my hands, I can post an update.
Here is the work that I've done. It is actually a joke how little I have needed to do to this car to keep my OCD in check, both cosmetically and mechanically.
I took the car for an early oil service and did coolant and brake fluid at the same time.
The only failure I've had so far as pre-cat O2 sensors, apparently a common Z4 M issue.
The only major cosmetics I've done are replace the gear knob and steering wheel because the rest of the interior was so nice, the factory fresh experience was within reach.
