Thanks for the post. It was great to watch after having been there on the weekend. I recognized some of the cars, and recall discussing a couple of the turns with the owner of the grey Boxster you pass.
Great video — I also spotted the grey/silver 987 Boxster around 11:40. Being a 987 owner myself I was particularly interested in the spoiler retracting in 5 and deploying again as you passed. Inside the car you never know if it is working!
I tried that but from what I can tell you have to remember to do it every time because turning off the ignition (actually I think turning on the ignition) seems to put it down and reset to automatic mode. With lots of other stuff to remember that was at the bottom of my list.
