I was out at Boundary Bay Airport this morning to see where the Wednesday events take place and found that BMW was having a comparison drive today. They have a fancy tent set up and a pylon course laid out. I saw several cars plus a couple of their bikes there plus an Audi and a Porche Cayanne. Unfortunately it looks like it is an invitation only event. Didn't stick around long enough to see anyone making runs on the course but I'm sure it could be interesting.
last sunday was the porsche club event on the lot next to ours - our autocross is 10x better than these invitational events, even though the cars may not be as nice!
