Took me a while to notice this thread, but........HI ALL!
Yep - I'm in Holland, too m2.
I've seen a silver 6 parked at a house in Zeeland, and also just today pulling out of Taco Bell on North River at lunchtime. Don't know if they're the same one or not. Blond woman was driving it - sport package, moonroof.
Also saw a black 6 last Wednesday about 9:00am driving down Butternut.
I've also seen a Steel Grey one a few weeks ago, on James, by 144th.
