I think no one here would like to buy 3ds max.
It's too expensive and you can find a crack for it.
I won mine from my father because he is engineer.
So..., about vray sp3, I haven't seen a crack for it, and "we" won't buy it. I think that 3ds max 2010 is a bad idea to start to work with lfs cars because mental ray is bad in my opinion.
The best 3ds max to use with vray is 3ds max 2009 I think. Because all materials from www.vray-materials.de works perfectly with 3ds max 2009 and not with 3ds max 9,8,7,...
No man.
There is no V-ray for it.
If you want Brazill go to www.splutterfish.com and download the Brazil v2 but it's too difficult to render and to configurate it.
Have fun
