At SEMA this year we showed you the finished prototype of Agent 47′s Harbinger Mustang, a dedicated track car the company will be selling based off of a Dynacorn 1969 Mustang fastback body. The Harbinger had just been fitted with a 687 horsepower V8 and a 6-speed transmission and was ready for duty as a weekend warrior.

In fact, the car had already been on track at Southern California’s Willow Springs Raceway just a few days before, as evidenced by this video posted by Agent 47. The Harbinger looks – and sounds – like an absolute beast of a car, and the interior and under-body details are a work of art. Check out the video below to see the car in action.
