You mean the 1000hp, 4-speed drift car? You can use it for whatever you want, that allows group X cars. Although you won't be very successful with it.
We actually had a Race A at Tsukuba with this car, man that was something else. Got myself a win though. So I suppose that's 1 thing you can use it for.
I used it for the drift achievement (100,000 points IIRC) at Suzuka East, I doubt I'll use it for anything else but it's nice that the drift communities are represented with a good toy.
