I'm getting serious about buying my first new car ever (I've owned a lot of fun used cars, just nothing new), and I already know the Truecar price as top-end trick (thanks to carbuying.jalopnik), and the get-the-Internet-price trick. But I still think most of the Internet prices are slightly above where I would like to be (for example, I'd like to be out-the-door where the Internet price is). For the reason that they're about $500 from the Truecar price, I feel like there's a lot left on the table still.

Which brings me to my question: how negotiable is the dealership Internet Price? Could I reasonably expect to get the Internet Price out-the-door, if it's only $500 from the Truecar price?

Many thanks, fellow Opponauts.

P.S. My car falls under a $25K "Internet Price."
