Well, I crossed paths with it tuesday night, around 8:15pm.
It was this exact car. It had the "FIRST M5" license plate and gold BBS wheels.
I drooled over this car in the video, but in person it was even more beautiful. I have only been reinforced in my opinion that it is the best looking M5. It also sounded glorious. It was also DAMN quick. I was behind him went flat out on a long onramp, and so I matched...he slowly walked me, while belting out that straight six howl.
Yeah, I have to own one of these sometime soon.
