Buying a car can be exciting, but unexpected fees, confusing add-ons, and unclear pricing can make the process stressful. California has introduced new protections designed to help vehicle buyers understand what they are paying for before committing to a purchase.
The California Combating Auto Retail Scams (CARS) Act, Senate Bill 766 (SB 766), became effective on October 1, 2026. It introduces requirements covering dealer price disclosures, certain add-on products, and a new cancellation right for eligible used-vehicle buyers.
For anyone purchasing a vehicle in California, understanding these changes can help make the transaction more transparent. It is also important to remember that consumer purchase protections and vehicle title and registration requirements are separate processes.
What Is California's CARS Act?
California’s CARS Act is a consumer-protection law that establishes rules for covered licensed vehicle dealers selling or leasing eligible light-duty vehicles weighing less than 10,000 pounds.
The law addresses pricing transparency, misleading representations, add-on products, and certain used-vehicle return rights. Some transactions are exempt, including specified wholesale, auction, fleet, and commercial purchases.
Because the rules depend on the transaction, buyers should review the official California DMV CARS Act guidance rather than assume that every purchase is covered in the same way.
What New Rules Must California Car Dealers Follow?
1. Clearer total-price disclosures
The law requires the total price to be disclosed in covered advertising and in the first written communication that references a specific vehicle or financing terms.
For buyers, this means paying attention to the full quoted price rather than focusing only on a large advertised discount or monthly payment. Ask the dealership to explain what is included, which charges are government-imposed, and whether any optional products affect the total.
2. More transparency around add-on products
Dealers must follow the law’s requirements for disclosing optional add-ons and cannot charge for certain products that provide no meaningful benefit to the buyer.
Before signing, review items such as service contracts, protection packages, and other extras. Ask whether each product is optional, what it covers, and how much it costs. Do not assume an add-on is required simply because it appears on a dealership worksheet.
3. Restrictions on misleading sales representations
The law also addresses material misrepresentations involving vehicle pricing, financing, leasing, and availability at an advertised price. Keep a copy of the advertisement and written quote so you can compare them with the final agreement.
Can You Return a Used Car Within Three Days in California?
One of the most notable changes is a three-day cancellation right for eligible used-vehicle purchases priced at $50,000 or less.
However, this is not an unconditional return policy for every vehicle purchase. Eligibility depends on the law’s terms, including the type of transaction and applicable conditions. The law also establishes requirements concerning vehicle condition, mileage, and possible restocking charges.
Before relying on this right, check the current official rules and your purchase documents. Ask the dealer how to exercise the cancellation right, which return procedures apply, and whether any permitted charges could be deducted from your refund.
Do not assume that a vehicle purchased from a private seller automatically carries the same protection.
What Should You Check Before Signing a Dealership Contract?
A few practical steps can help you avoid misunderstandings:
- Compare the advertised total price with the written offer.
- Review every fee and optional add-on before signing.
- Read the financing or lease terms, including the total cost.
- Ask for clarification about any product described as mandatory.
- Keep copies of the advertisement, purchase agreement, and disclosures.
- Confirm who will handle the title transfer and vehicle registration.
These steps are useful even when a transaction is covered by the new law. Clear documentation makes it easier to identify discrepancies and ask questions before the purchase is finalized.
What Does the New Law Mean for Vehicle Title and Registration?
Dealer transparency rules govern covered aspects of the purchase transaction. They do not replace California’s vehicle title-transfer and registration requirements.
In many dealership purchases, the dealer handles at least part of the registration process. However, if the dealer does not provide those services, the buyer may need to complete the required registration steps. The necessary documents can include the title or title application, applicable signatures, fees, and other paperwork depending on the vehicle and transaction.
California generally requires ownership changes to be reported within 10 days, and the required fees must be paid within the applicable deadline. Review the DMV’s dealer vehicle registration guidance to understand what applies to your purchase.

What Should You Do if a Dealer's Charges Do Not Match the Quote?
Start by gathering the advertisement, initial written quote, signed contract, and any add-on disclosures. Ask the dealer to explain the difference in writing and identify the relevant charge.
If the issue remains unresolved, consult the official DMV guidance and determine which consumer-protection agency or qualified legal professional can address your specific concern. Whether a charge violates the law depends on the facts and applicable requirements.
