Crazy M3 Drifting

I just caught wind of a pretty cool video showcasing the E92 M3, E46 M3 and Nissan Nismo. They're drifting through what I presume to be a retired army base of some sorts? But the video editing is quite good with many camera angles. The drifting is superb! They really do some crazy things in there and the soundtrack behind it really puts the whole thing together. Check it out for yourself!
