On October 1, California Buyers Can Hand a Used Car Back. Today That Right Costs Up to $250.

If you’re shopping for a used car in California and the car will keep until October 1, let it keep. On that date you get three days to change your mind, and for the first time you don’t have to pay for the privilege.

Right now, changing your mind is a product the dealer sells you.

California dealers have to offer a “contract cancellation option” on used cars priced under $40,000. You buy it: $75 on a car up to $5,000, $150 up to $10,000, $250 up to $30,000, and one percent of the price above that. What the money gets you is until close of business on the second day after delivery.

Read that again. The right to walk away from a bad car deal is currently sold to you by the person who sold you the car.

Senate Bill 766, the California Combating Auto Retail Scams Act, repeals that section outright. Starting October 1, 2026, a three-day right to cancel comes standard on every used vehicle a dealer sells at $50,000 or less. Higher ceiling, an extra day, nothing to buy.

Here’s the catch, and it’s a reasonable one.

Cancel and the dealer keeps a restocking fee: 1.5 percent of the sale price, never less than $200 and never more than $600. Drive more than 250 miles in those three days and they can add a dollar a mile on top, capped at $150. Worst case for walking away is $750. On a $20,000 car you kept under 250 miles, it’s $300.

Two hard limits. Past 400 miles the right disappears entirely, no partial credit. And the car has to come back in the same condition, allowing for reasonable wear and tear and for any defect or mechanical problem that becomes evident while you have it.

That last clause is the one worth memorizing. If the transmission starts slipping on day two, that’s a defect that became evident. It doesn’t cost you the return.

Three hundred dollars to undo a $20,000 mistake is cheap. The old version, where you paid $250 up front for two days on a smaller set of cars, was dumb, and openly so.

Two ways to play this.

If you’re mid-shop and the car will still be on the lot in five weeks, wait. You gain a wider price band, a third day, and the option price back in your pocket.

If you can’t wait, buy the cancellation option anyway. It’s the only version of this right that exists before October, and under the current law the dealer has to apply what you paid for it toward the restocking fee if you actually cancel. That makes it close to free insurance if you use it.

On or after October 1, look for a separate page titled “3-Day Right to Cancel Used Car Purchase or Lease.” The dealer has to hand it to you as its own document, not a clause buried in the contract. If it isn’t in the stack, ask where it is before you sign anything else. Traded a car in? You get it back, or its value, within 48 hours of cancelling.

Two limits worth naming. It’s California, and it’s dealers. A private-party sale off a classifieds listing carries none of this, then or now.

If you’re financing, run the payment through the loan calculator before you sign, not after. And SB 766 does more than hand you three days: on the same morning it rewrites what the advertised price has to mean.
