<prompt> Human: Im out shopping for cars, paying cash only... but how do I know what is a reasonable amount to negotiate with a typical used car dealer? Ideally purchasing from a private seller seems better, but its nearly impossible to find the vehicle with the options we want that way without a bit of luck or a lot of patience.Its challenging to figure out what the best price is, because the rates at every dealer on the internet seem inflated. Is it realistic to push 10 off the listed price of vehicle? 15? At what point will they just laugh at you? Ive done some internet searches and it seems like there is some magical formula to the pricing that I cant quite figure out... how do I get the best deal?  <response>: Car negotiation has changed a lot with the internet, dealers typically dont make a ton of mark up on any cars, and make most of their money with financing and service. Price out your potential vehicle online, and do most of your shoppingnegotiations online. Typically dealers will give best price within a few hundred these days.
