Most dealers, if they even ask, will want 500-1000 refundable deposit to "hold" an order just to keep the tire kickers at bay. Many buyers that have a prior good relationship with their dealer won't even have to do that. A dealer that asked for $2,000 should be watched carefully that they don't try to add any BS fees on the deal. This isn't a pricing thread, but Invoice-holdback is the absolute least you should be paying.
FWIW, I put a small deposit down with my order, then on delivery when asked about a "down" I asked if I could put it on a CC (that I pay off monthly). "Sure!" Then they tried to back-peddle when I told them to put $30K on my Visa saying they couldn't do that much. They finally relented after playing a pricing game on a Maxcare.
