I was traveling along the autobahn today and happened upon what looked like the new SLS Black Series at the link below:
The car had some camo attached to it but after searching utube, it looked very similar (but who knows, could have been a tuner-house's project car). Sorry no pics, I was too busy trying not to crash.
Anyway, we danced a bit in the high speed lane but even at full throttle acceleration, the M couldn't keep up with that massive Merc. Afterwards he slowed down and we each gave the other a thumbs-up.
Needless to say, a great time with a pretty sweet car.
10 minutes of fun on the bahn @ 160 mph = 1/4 tank of fuel :-)
