Nice !
Make sure the oil level does not drop too low as it can cause the chain tensioner to collapse.

Often referred to as the “Death Rattle Noise”, this audible sound coming from the engine bay is the timing chain in your R55, R56, or R57. When you first start your car you may experience a noise coming from the engine bay on a cold morning, once the engine warms up the noise may go away. If you lift your hood up that noise is coming from the front of the timing cover. One of the possible causes for this noise occurs when the timing chain support rail loses tension. This support rail is made of a durable plastic, but with heat and time, the plastic can become brittle and break

I have a 2006 MCS with 140,000 miles on it that is my DD.
Only towed twice- Harmonic Balancer failure and a Super-Charger failure.
Other issues outside of routine maintenance was the alternator being replaced at 104,000 miles, lower control arm bushing replacement, brake pad sensor connection disintegrated, speedometer/tachometer cluster sometimes stop working on a random basis and the airbag module failed.
Getting ready to replace the struts and lower motor mount this weekend.
Have fun :-)
