A used car is the second-biggest purchase most Californians ever make — and the one with the most ways to get burned. Flood cars from out of state, rolled-back odometers, “certified” inspections that certify nothing. Here’s how to buy smart under California law.
Before you shop: know the rules
- California dealers must give you a written contract with all terms disclosed — price, down payment, finance charge, total of payments, and payment schedule (Civil Code 2982, the Automobile Sales Finance Act).
- The Buyer’s Guide is federal law. Every dealer must post the FTC Buyer’s Guide on the window of each used car, stating whether it’s sold “as is” or with a warranty and what that warranty covers. No guide on the window? Walk away.
- “As is” doesn’t mean “no rights.” Even an as-is sale can’t disclaim the implied warranty of merchantability under the Song-Beverly Consumer Warranty Act if the dealer knew about serious defects — and fraud is never disclaimed.
- Smog certification is the seller’s job. In California, the seller — not the buyer — must provide a valid smog certification at the time of sale (with limited exceptions for transfers between family members).
The 10-point inspection checklist
Do these before money changes hands:
- Run the VIN. Get a vehicle history report (Carfax, AutoCheck, or the free NICB VINCheck for total-loss and theft records). Look for salvage titles, flood damage, and odometer discrepancies.
- Check for open recalls at nhtsa.gov/recalls. Dealers must disclose unrepaired safety recalls.
- Get a pre-purchase inspection from an independent mechanic — not the dealer’s shop. $150–$200 buys you the truth about the engine, transmission, frame, and electronics.
- Test-drive like you mean it. Highway speeds, hard braking, tight turns, full A/C and heat, every button and switch.
- Check the title in hand. Match the VIN on the title to the VIN on the dash and door jamb. Liens? Salvage brands? Walk away if anything doesn’t match.
- Look for flood and accident signs. Musty smell, silt under carpets, mismatched paint, uneven panel gaps, new carpeting in an old car.
- Verify the odometer. Compare the mileage to the history report and service records. Odometer fraud is a federal crime — report it to the DMV.
- Confirm smog certification. Ask for the certificate before you sign. No cert, no deal.
- Get everything in writing. Verbal promises about repairs, warranties, or “we’ll take care of it” are worthless. If it’s not in the contract, it doesn’t exist.
- Sleep on it. The deal that’s “only good today” is designed to stop you from thinking. Real deals survive the night.
At the dealership: the paperwork gauntlet
- Read every line of the retail installment contract. Verify the price, down payment, APR, term, and total cost match what you were told.
- Decline the add-ons you don’t want. Extended warranties, GAP insurance, paint protection, VIN etching — each is optional and often wildly overpriced. Say no, or negotiate hard.
- Watch for spot delivery. Don’t drive home “pending financing” — see our guide on yo-yo financing scams.
- Keep copies of everything you sign. California law entitles you to copies on the spot.
Buying from a private seller
Private sales are “as is” by default in California, so your inspection matters even more. The seller must still provide smog certification, sign over the title properly, and report the sale to the DMV within five days (you must register within 10). Never pay cash without a bill of sale, and meet at the DMV or a bank — never a parking lot at night.
