I just bought one a few weeks back and it is an instant rebate. The only difference with it being cash back is that the tax is calculated before that amount is deducted. And it can not be combined with any other offers like the GM supplier etc. Keep in mind that that money is coming from GM so you can still negotiate with the dealer to get more money off. Good luck.
