From Price Feed to Deal Jacket: Building a Defensible Advertising Audit Trail Before California's CARS Act

The California CARS Act, formally the Combating Auto Retail Scams Act or SB 766, takes effect on 1 October 2026. Most of the coverage so far has been about what dealers have to disclose. The harder problem is what they have to keep, and for how long.

SB 766 requires two years of records showing the dealership complied. Every store already keeps its contracts. What the Act asks for is the advertisements, the communications and the price disclosures that led to them. That is a different filing problem, and most stores have no system that answers it.

What the California CARS Act requires

SB 766 adds Civil Code section 1784.1 and following, and amends section 2982 covering conditional sale contracts. Its central requirement is that a dealer disclose the total price clearly and conspicuously: in advertising, in the first written communication with a consumer, and during negotiation.

Total price means the base sale price plus dealer-installed items and price adjustments. Certain taxes, government fees and rebates sit outside it. Where a dealer quotes a monthly payment, the disclosure has to carry the total amount paid over the term. It also has to state the assumptions behind that figure, including down payment and trade-in value.

It applies to dealers as the Vehicle Code defines them, in retail sale and lease. Wholesale transactions, fleet sales, commercial purchasers, and vehicles rated above 10,000 pounds gross weight are outside it.

The two-year record

Records must be kept for two years from the date each one is created, and they have to demonstrate compliance rather than merely exist. The categories are broad:

• Advertisements, including online listings showing a vehicle's price
• Communications with consumers, including price disclosures given in writing
• Contracts and the documents behind them, including deals that never closed
• Add-on product documentation
• Cancellation requests and refunds
• Written complaints received

A store can produce any signed contract from the last two years within minutes. Ask it for the listing that vehicle carried on a marketplace eleven months ago, on the day the customer first saw it, and the answer is usually that nobody kept it.

Where a price drifts

A vehicle's price does not live in one place. It is created once and then copied, and each copy is a chance for the number to move:

1. The DMS or inventory tool, where a used car gets priced after reconditioning.
2. The syndication feed, which pushes that price out on a schedule, often overnight.
3. The dealership website, which may apply its own conditional offers, incentive stacking or payment calculator on top.
4. Third-party marketplaces, each with its own field mapping, refresh interval and display rules for fees.
5. The CRM quote, produced by a salesperson who may be working from a screen, a printout or memory.
6. The final contract, built in the F&I office, where add-ons and adjustments land.

None of those steps is misconduct. But a price cut on Friday afternoon that reaches the website immediately, the feed on Saturday morning and a marketplace on Sunday leaves three different numbers in front of the same shopper over one weekend. Under SB 766 the dealership has to be able to show what each of those surfaces said, and on which day.

What a defensible trail looks like

A dashboard showing today's prices says nothing about last November. A dated record of what a listing said on the day a customer saw it is what the Act asks for. Four things get you there:

• One source of price. If the website, the feed and the CRM each calculate a total independently, they will disagree eventually. One system should own the number and the others should receive it.
• Capture the listing, not the number. The disclosure lives in the layout, the fee line and the asterisk, so the retained record has to be the rendered listing rather than the price it displayed.
• A link between the listing and the deal. Two years later, the question is about one customer and one car. A record that cannot be joined back to a stock number and a date is an archive rather than evidence.
• Reconcile before delivery. Comparing the advertised total against the contract total while the deal is still open is a correction. Finding the gap afterwards is a disclosure problem with a signature on it.

The next ten days

Anything that takes a quarter to build will not be ready. Three things will fit:

Take a baseline. Pick ten vehicles across price bands and compare the total shown on the website, on each marketplace, in a CRM quote and on a recent contract for a similar unit. The size of the spread tells you whether this is a records project or a pricing project.

Find out what your vendors already retain. Website platforms, syndication providers and marketplaces each hold some history. Ask, in writing, what is kept, for how long, and whether the dealership can export it. The answers usually differ from what the sales rep implies, and vendor oversight is a compliance obligation in its own right.

Decide who owns the number. Pricing, marketing and F&I all touch it, which usually means nobody is accountable for the six of them agreeing. Name a person before 1 October rather than after the first complaint.

What this does not change

SB 766 is a California statute, so it binds stores selling into California. A group with rooftops in several states can either hold one standard everywhere or run two sets of rules, which is the same choice that group-wide compliance poses everywhere else.

It also sits alongside obligations a dealership already carries rather than replacing any of them. The FTC Safeguards Rule still governs customer information, and the federal lending statutes still govern what the F&I office discloses. Advertising records join the list of things a store has to be able to prove about itself two years later, which is what risk management amounts to in practice.

A store advertising honestly across all six systems still fails the records test if it cannot demonstrate it. That is the more common case, and the one worth checking before 1 October.
