Consumer Reports came out with a study that said 40% of car buyers were not informed of rebates and 60% weren't told of available lower financing. Of course dealers were outraged at this claim even though the publication says some of the problems could be honest mistakes. I would think most buyers these days consider the incentives/rebates when shopping for a particular vehicle. And the other side is I just think a lot of salesmen do not pay attention to their jobs. I've met many a salesman who know less about the car they're trying to sell me than I do. So it's not too hard to postulate they don't know about the latest incentive the manufacturer has just released either.
