Can I return a car I just bought in California?

Generally no. There is no general cooling-off period. Qualifying used-vehicle purchases may have an optional two-day cancellation agreement available for a fee, which must be purchased at the time of sale.

What is spot delivery or a yo-yo sale?

It is when you take the car home before financing is finalized and are later asked to sign new terms. Ask whether your contract is conditional on financing approval, and get the answer in writing.

Can a dealer charge whatever they want for the doc fee?

No. California caps the dealer document processing fee at a set dollar amount. If a fee labeled similarly is higher than that cap, ask what it actually covers.

Should I buy add-ons like paint protection or GAP at signing?

Only if you've priced them and decided they're worth it on their own terms. None are required for financing, and you can often buy comparable protection products elsewhere for less.

What a California dealer must hand you at signing

Read these four documents before you sign, and know which fees are capped by law.

The finance office is where a good deal quietly becomes an average one. Nothing here is about distrusting the dealer. It is about being the customer who reads the numbers, because that customer gets a better outcome every time.

The documents that matter

The purchase contract, which is the only number that counts. Verify the vehicle price, trade allowance, payoff amount, down payment, APR and term.
The itemized fee schedule, so you can see doc fee, registration, and any add-ons separately.
The Buyer's Guide window sticker on a used vehicle, which states whether it is sold as-is or with a warranty.
Any service contract, GAP or protection product agreement, with its price shown as a dollar amount rather than a change in monthly payment.

Fees you should recognize

California caps the dealer document processing fee, and the cap is a set dollar amount rather than a percentage. Registration, title and license fees are pass-through amounts set by the state. Anything else on the line is negotiable by definition.

Electronic filing fees are also regulated. If you see a large, vaguely named fee, ask what it is and what law sets it.

Add-ons you can decline

Paint and fabric protection, nitrogen-filled tires, VIN etching and dealer-installed accessories.
Extended service contracts and GAP, which are legitimate products but are optional and negotiable.
Any product presented as required for financing. Coverage requirements come from the lender in writing, not from the desk.

California specifics worth knowing

There is no general cooling-off period for vehicle purchases in California. Once you sign, the car is yours.
For qualifying used vehicles, dealers must offer a two-day contract cancellation option for a fee. It is optional and it has conditions, so read them.
A contract that is contingent on financing approval can be unwound if the financing falls through. Understand which kind you signed before you drive off.

The one habit that saves the most money

Negotiate the out-the-door price, in writing, before you discuss monthly payment, trade or financing. Payment-first negotiation hides term length and add-ons, and it is the single most reliable way for a deal to drift.

Trade-in paperwork

If you're trading in a vehicle, confirm the trade allowance and any remaining loan payoff are itemized separately from the new purchase price. A trade rolled silently into the deal makes it much harder to see whether you got a fair number for it.

The short version

Read the contract, not the payment. The doc fee is capped, add-ons are optional, and California has no general cooling-off period, so everything gets settled before you sign.
