I spotted this weird Porsche SUV. Could this be some Cayenne-successor? There were two, plus a Cayenne Turbo...
^ With Cayenne Turbo
^ Two Mystery-Porsches + VW Wagon which was together with them for quite a while.
Also spotted today:
^ Some race-tuned Mercedes...
^ Slightly Ricey-looking old BMW 3-series, probably not an M3.
^ An Aston-Martin/Jaguar I don't recognize.
^ Two Porsches, old and new, which seemed to race each other.
EDIT: Is it just me, or does the 'ring seem very empty lately? The whole week wasn't very full when I checked.
EDIT 2: Porsche Mystery-car strikes back...
...And gets bumped by the 911:
