Dealers not dealing

I went out today with a friend to try to buy a new Hyundai. We went to 3 dealers including one that I have bought 2 Sonatas from in the last 5 years. They are not dealing at all. They would basically take the list price (sometimes the invoice) and subtract the rebate and try to sell it at that price. No amount of haggling and counter offers could get them to budge. We did get them to go down another $400 when working on a 2009 Elantra. We went from 2010 Sonata, 2009 Sonata, 2010 Elantra to 2009 Elantra. They just didn't want to sell at all. I am used to getting a least 2K plus rebate off of the invoice. We stopped by a Toyota dealer and without any haggling he got an offer to buy a Corolla cheaper than the Elantra. The Camry was almost the same price as the Sonata. He's owned a Toyota before and I think he's probably going to wind up with another one. I think they sold so many cars during the cash for clunkers that they are not very hungry. They didn't have very many 2009s left, the C4C pretty much cleaned them out. Has any one else run across this problem, I'm wondering how long this is going to last. If its permanent, I may have to look elsewhere for my next car. Anyone got a good deal in the last couple months? Does anyone know how the Manufactures' incentive (dealers payback) program works? I figure that the dealers have already hit the numbers they need for the max incentive payback for this year. Maybe it will reset at the beginning of the next year.
