California Car Buyers: On October 1, the Advertised Price Becomes the Real Price.

Update, September 6, 2026: We were vague about the cancellation right in this post’s FAQ, and it matters, because the right stops costing money on October 1. Today a California dealer must offer you a contract cancellation option on a used car under $40,000, and you buy it: $75, $150 or $250 depending on the price, or 1% on cars between $30,000 and $40,000. From October 1 the three-day right comes with the car, covers anything up to $50,000, and costs nothing unless you use it. Full detail added below.

If you are buying a car in California and you can wait until October, wait.

On October 1 the price in the ad becomes the price. Not the teaser number that turns into something else once you are sitting at the desk with a pen.

What the law does

SB 766, the California Combating Auto Retail Scams Act, became law on October 6, 2025 and becomes operative October 1, 2026. Three things change. The total price has to be clear and conspicuous in any ad that names a specific vehicle, in written pricing or financing communications, and in the dealer’s first response about a car. When an add-on comes up in writing, the dealer has to tell you the add-on is not required and that you can buy the car without it. And charging for an add-on that gives you no benefit becomes a violation.

The bill names examples of the third one. Tires sold to you as nitrogen filled that are not at least 95% nitrogen. Oil changes on an electric car.

Somebody had to write that down in a statute.

The right to change your mind stops being a product

Here is the piece that got buried. California has had a cooling-off period on used cars since 2006, and it has never been free. Vehicle Code 11713.21 says a dealer cannot sell you a used car under $40,000 without offering a contract cancellation option, and the price schedule is written into the statute: $75 on a car up to $5,000, $150 up to $10,000, $250 up to $30,000, and 1% of the price between $30,000 and $40,000. Buy the option, and you get until the dealer’s close of business on the second day to bring the car back.

Do not buy it, and you have no right to return the car at all. Which is how most people end up with no right to return the car at all.

From October 1, SB 766 replaces that with a three-day right to cancel that comes attached to the deal. The dealer cannot charge you for it. It covers used vehicles at $50,000 or less, up from under $40,000, and you lose it once the car passes 400 miles since you signed.

If you cancel, the dealer can charge a restocking fee of 1.5% of the sale price, no less than $200 and no more than $600, plus $1 a mile for anything over 250 miles, capped at $150. Under the old rule the restocking fee capped at $500, but the option fee sat on top of it.

Run it on a $28,000 used car. Today you pay $250 for two days of second thoughts, and you are out that $250 whether you use it or not. On October 1 you get three days for nothing, and $420 only if you actually hand the keys back.

Smart. And it means the same car costs $250 less to be careful about in October than it does this week.

The part nobody put in the press release

Washington wrote this rule first. The FTC finalized its CARS Rule in January 2024, covering the same ground for the whole country. The National Automobile Dealers Association and the Texas Automobile Dealers Association sued. On January 27, 2025 the Fifth Circuit threw the rule out because the FTC had not issued an advance notice of proposed rulemaking that its own procedures required.

Not because the disclosures were wrong. Because of a missing step in the paperwork.

So the protection you were about to get nationally now depends on your zip code. California brought it back for its own buyers. If you live somewhere else, nothing changed for you on this.

What the add-ons actually cost you

The dealer rolls add-ons into the loan, which is where they stop feeling like money. Finance $2,000 of paint sealant, etched glass, and a service contract you did not ask for at 7% over 72 months and you pay about $2,455 by the end. That is the sealant plus roughly $455 in interest for the privilege of not noticing it. Run your own numbers on our loan calculator before you go in.

Do this

Ask for the out-the-door price in writing before you set foot in the showroom. That works today and it will still work in October.

If you are shopping in September, assume none of this protects you yet, and read the second page of the buyer’s order line by line. Anything you did not ask for, strike it and initial it.

If you are signing before October 1 on a used car and you want a way out, you still have to buy the cancellation option, and you should. Two hundred and fifty dollars is cheap against the wrong car. If the purchase can wait three weeks, waiting is worth that $250 and an extra day.

After October 1, treat the advertised price on a specific car as the number. If a dealer walks it up with mandatory packages, that is now a disclosure violation, not a negotiating style.

And if you are financing, shop the loan separately from the car. Our auto loan guides and the best loan rankings exist because the dealer’s finance office is the most expensive room in the building. We ran the math on what stretching to 84 months really costs last week: about $3,500.
