Well i used to sell in the used car department but i do know that there isn't usually much room under invoice. Just due to that's what the dealer was "supposed" to pay for it. now of course there are discounts when the dealer buys a lot at once but it's usually not a whole lot cheaper. There are many other factors there also. Such as "flooring" which is a term that just means "intrest." Basicly the dealer doesn't purchase all the cars on their lot. The use the bank and the long they are on the lot the more the car cost them to buy. There is also what they call "manufacture kickback." Which is just that if they have a good CSI score with their customers for every car they sale the manufacturer will give them money. usually 100-300 bucks. Honestly your best bet unless you need the perks of "new car financing" like the rebates used as a down payment and other perks it's better to buy at least a year used. You can litterally loose thousands (depending on the price of the car) just buy rolling the car off the lot. On average 5-15% of the purchase price. But if you don't want to buy used then by all means buy new. Personally i'd shoot for under invoice but wouldn't be surprised if they won't do it. Just me experience in that world. Good luck
