The Mercedes-Benz C63 AMG Coupe Black Series is a whole lotta car. Not only is the name a mouthful, but the 510-horsepower German rocket can be a handful too, well, in the wrong hands. This wouldn't be the first time we've seen techs or valets getting their kicks behind the wheel of a vehicle that doesn't belong to them, but it seems some employees at one Ottawa-area dealer didn't get the memo.Our tipster claims that a couple rogue techs at a dealership called Star Motors (formerly Carling Motors) decided to take out one of the 30 existing Black Series in Canada for a joyride. While we agree that some test drives of performance cars should be spirited to find performance-related problems, it's pretty clear these guys just wanted some kicks behind the wheel of this $115,000+ Autobahn assassin.For over eight minutes they negotiate the streets of Ottawa near the Hunt Club Road dealership, breaking all kinds of laws, risking property and injury in the process. The police would gladly impound this Black Series for some of these speeds, and MB enthusiasts would gladly slap these guys in the face for redlining the motor for so long.Why any tech would post this on YouTube is beyond us, as they're are only asking to be fired. The Internet has moved in for some e-justice and MBWorld.com has been set ablaze with nasty comments on the matter. Not only did they identify the location of the dealership, they have also sent the video, the original of which was removed from YouTube but then re-uploaded by a forum member, to Mercedes-Benz Canada HQ and are hard at work trying to find the possible owner to show him what's been done to his car pre-delivery.
