Drift yourself in single player mode, then just copy the second car to the video from the car you drove somehow and there you go, perfect twin.
Or put the same clip 2x to the video, one running a bit behind of the first one, and make both visible? Not sure though what I just said.
Yes, looks like aston martin to me in some way, I don't know why though, he has alot more of those funky mod videos there, what I've seen long time ago though, but it's still funny to watch them.
