Ha, I was there too but I had to leave right after the track opened, as my rental was due for return at Munich airport at 6pm on Sunday. What a wasted morning with the fog; I have 11 laps left on my ticket but I am moving home Friday so I won't get to use them. I was suspecting it was going to be crazy for the first hour or so after things got moving, as it was I could barely get out of the parking lot to leave there were so many people waiting to get on track.
Nice laps, btw. The car sounds great! Where were you parked? I only recall seeing the white M3 with the Hamman stuff on it over by the ticket shed, and another white one behind the Ring-taxi stand.
