Car prices are the same as any other consumer goods prices: there is a MSRP and, unless it's some rare, high demand model, you can always buy at the MSRP. Unlike other consumer goods, though, it is worth haggling because the retail markup is in range of several thousand dollars and the dealer is interested in your business (maintenance, warranty repairs) enough to forfeit a part or the whole markup. Depending on the incentives, a dealer might be even considering selling under the invoice price. Also there are other components of the deal, not happening often with other goods: trade-in and financing. You cannot put a fixed price on those.

But if you really don't care and want to buy a car for cash at MSRP you can do it with little to no hassle.
