Section 179 tax deduction

[GPSnV1]

I have been wandering around wondering about what will follow my 2004 4.4i sport X5. I noticed in the sticky for the E70 - http://www.xoutpost.com/x5-e70-forum/...l-pricing.html - several saying that the rules for the Section 179 tax deduction have radically changed.

Can someone help me with this? Does this go back to my 2004 X5 or just those purchased this year? Or even if it goes back to the 2004, is 2007 the first year the changed are to be implemented or is it later?

I ask because this was a major benefit to me in getting the X5. But if I am cut free from that tax return, then the world looks different. One post says there are other ways to go at this, but gives no leads.
