Four ways to buy a new car in California
You can reach the same car four ways. Here's who does the work in each one.
There are four realistic ways to end up in a new car in California, and they differ less in price than in who does the work and who holds the leverage.
Walking into a dealership is the default. You see the car, you drive it the same day, and you negotiate alone against someone who negotiates for a living. The price you get depends almost entirely on how much you enjoy that conversation and how much time you are willing to spend having it at several stores.
Buying online from a fixed-price retailer removes the negotiation entirely. The number you see is the number you pay. That is genuinely restful, and it costs you whatever discount a negotiation would have produced.
A buying service through a membership organisation pre-negotiates a price with participating dealers. You still go to the dealer, and you still sit through the finance office, but the headline number is settled before you arrive.
A licensed broker works the other way around: you never go looking. You say what you want, the broker sources it, negotiates it, and brings the paperwork to you. In California a broker must be licensed and must put a brokerage agreement in writing for each transaction, which is worth knowing whoever you use.
None of these is automatically cheapest. The honest way to choose is to ask how many hours you are prepared to spend and how much you want to be the one arguing.
