I asked that question when I ordered my truck. "What happens if there is a MSRP/Invoice price increase between the time I place the order and the time its delivered?" My salesman told me the agreed price is the price they would sell it to me. He also mentioned that I would be eligible for any rebates that came in before it was delivered. They then gave me a printout that listed the sale price with taxes and dealer fees, less my deposit. So I knew exactly what funds I needed when I went to pick it up. Luckily my truck was delivered about a month after I ordered it so I didn't have a pricing issue. I know every dealership is different but I'm pretty sure they would not have raised my price if the MSRP increased for some reason.
