S62 Powered 2003 BMW E39 540i Touring M Sport 6 Speed Wagon - Cold Start Exhaust & Sunroof Operation

Cold start of the S62 M5 powered 540i M Sport, Speed manual Wagon.
Purchased by my consignment client on BaT in March of 2019 for $75,000+.
I use the remote to unlock the car as I walk up to it.
Cold start.
0:42, I open up the straight exhaust with a press of the remote button from inside the car.
0:59 I close it again, you can easily hear the difference between the 'muffled' exhaust and straight through. I'll do the same during the test drive video.
1:12 is the sunroof operation demo, it works fine... sliding back and forth as well as in the 'vent' mode.
