If I'm allowed to go backwards in time...
For the first time, I parked next to another RS6, at the Rolex 6 Hours in Watkins Glen. His was mostly stock, aside from the MTM ecu/tcu tunes.
In May, I saw Felipe Massa in Montreal after the F1 race. Not a rare or exotic car, but he does drive one.
Then there was a Bugatti Veyron turning onto the Champs Elysees, just after I had mentioned that you could see any car at any time on this street.
I always have a camera with me because photography is one of my biggest hobbies. I could post hundreds of pics that I've taken just in the last three years, but could limit it to events moving forward if you like.
