Surprised we didn't have one of these yet but here goes:
Yesterday afternoon (12:30 ish) spotted a Black (De-badged) M5 getting on I-5 North from one of the rest stops. This was just past the Vancouver Area. We gave each other a thumbs up and even got to "play" a bit on the way to Seattle/ Tacoma. Good times. Definitely helped on an otherwise boring drive.
I was wrapping up my 3,000 mile road trip as I had been in Vegas all week for a Work Conference.
Anyone here?
