I have spent more hours than I care to count on many of the M3 forums and websites and had never seen this video.
The sidegrill and blackout trim are clearly visible on the car, and the V8 sounds incredible. Clearly a 6-speed manual (last segment of video has 2-3 upshift (maybe 3-4) that is NOT SMG quick).
Click and enjoy.
Has anyone seen this exact video before?
