Most definitely a promo. Too many unexplained jerks of the camera, shooting from behind a wavering tree branch (that could be avoided by the cameraman moving inches to the side), too many cuts to new shots "just when it was about to get juicy" and so on. If it's meant to be disguised as a spy video, the disguise was done very badly.
From what I have read/heard this is the SLR Roadster 722 edition. But it could be a replacement, I guess we will just have to wait and see.
Why all that camo fuss if its just the 722? And what about the behind-the-head things? This is an older video however is another look at what M-Benz is doing. http://www.youtube.com/watch?v=QGgmMLSxC4w&feature=related _J
To me, it looks like the Mercedes Carver they debuted several years ago. It was a "look what we can build" car never meant for production. Suspension leans into turns like a bike. Mark PS: for some reason FChat wont allow me to attach the pic but you can google it.
The rear things..maybe roll bars? Like I said, I dont know that it IS the Mercedes Mclaren SLR Roadster 722, That is just what I read/saw on another site. Mercedes Carver like Joker was talking about. Image Unavailable, Please Login
