Tom,
You wrote,"You should always get 10% off list.ALWAYS". That depends on the vehicle. But, it is true that you can normally buy at or near invoice. However you miss the point. GM is not talking 10% but 15% to 25%(with other incentives)the buyer gets the vehicle well under dealer invoice. And in the past if you got Employee price you could not get GM card credit, during this promo you can. IT IS A VERY GOOD SAVINGS.
