@husker boxster: I was in Blue on Sat & Sun, and you were looking for the wrong car
It's a meteor grey 2009 C4S. We actually "met" ;-) a couple of times on the track in the Blue group on Sunday. IS this a Cayman S or R?
Below is a picture on how I fought the sound limit (I have permanent PSE too).
By the way: We actually DID meet. remember the grey Carrera that accidentally parked on your spot on Sunday? That was me! I was all packed up and was ready to go but then had to follow the "call of nature" and thought your spot was empty. I noticed the Omaha plates, but didn't menatlly make the connection.
Bummer
