I DL it the other day; it's free to play with option to buy more cars and tracks.
You need Steam to make it work; I DL it and then it did an upgrade with 6.2GB of data.
I then found out that it DL all the material but then you need to buy some of it to be able to use it; when you buy it you can immediately use it.
The sound experience is pretty amazing.
