GM offers rebates in addition to employee pricing

This is quickly becoming a price war, with GM having announced it will offer cash rebates on many 2006 and 2005 cars and trucks, in addition to the employee pricing it already offers on nearly every 2005 model. The rebates range from $500 to $1,000 on the 2006 models and up to $3,000 on remaining 2005 models.
GM is leading the way in creative pricing, but is it working in the way it was designed? Is GM's current strategy increasing sales by bringing the price of its lineup more in line with its perceived value, or is this strategy really causing consumers to consider what the General has to offer who otherwise wouldn't? We're wondering specifically if those people who would never consider buying a GM vehicle would do so now. Anybody in that camp care to comment?
