Little update -- officially entered 'keep-it-forever' territory on the way home from the airport after a work trip (even timed it with the clock):
The car is still treating me extremely well after all this time -- have a few scheduled maintenance items on the horizon with the mindset of long-term ownership (DCT service, brake service, diff service etc), but oil analysis reports continue to come back promising. Will likely be refreshing suspension components in the spring, and start to recondition the rest of the car as I start to look for the eventual add-on car, and preserve the M6.
Here's a recent photo before the fall, she still is looking good after roughly 8 years and 100,000 miles since new:
