To buy a used car, set an out-the-door budget, compare financing and insurance, and shortlist vehicles that fit your needs. Confirm the VIN, title, history, and open recalls. Test-drive the car and arrange an independent inspection before committing. Use comparable vehicles and repair estimates to negotiate, then verify the written price, financing terms, warranty, and transfer documents before you pay.

1. Set your complete budget
The price on the windshield is not what the car costs you. Your real number is the out-the-door (OTD) price: the selling price plus sales tax, title, registration, and dealer fees. Insurance and financing add ongoing cost on top of that. And keep a separate repair reserve — money you do not spend at the dealer, held back for the first tires, brakes, or surprise repair a used car eventually needs.
Keep the repair reserve out of your purchase total. Folding it in is how buyers talk themselves into a more expensive car than they planned for. Work out what you can actually afford before you shop.
| Negotiated vehicle selling price | $21,000 |
| Dealer documentation fee | $400 |
| Sales tax (assumed 7% of price + doc fee) | $1,498 |
| Title & registration (assumed combined) | $250 |
| Optional products | $0 |
| Illustrative OTD purchase price | $23,148 |
Assumptions: no trade-in or rebate; hypothetical tax base of $21,400. This is arithmetic for teaching, not a state tax quote. If you put $3,000 down and finance the rest, the amount financed is about $20,148 — but the OTD purchase price is still $23,148. Selling price, out-the-door price, and amount financed are three different numbers; keeping them separate prevents an expensive mistake.
2. Compare financing and insurance before you shop
Get a financing pre-approval before you walk in. When you already have an APR from your bank or credit union, the dealer’s offer has to beat a real number instead of an imaginary one. Compare offers on the rate and APR, the term, the amount financed, and the total cost of the loan — not the monthly payment, which a longer term can make look small while it quietly costs you more.
Your credit tier drives the rate, so it pays to know where you stand. See how your credit score affects the APR, and get insurance quotes on the specific cars you are considering — premiums vary a lot by model. The CFPB’s guide to comparing auto-loan offers walks through what to look at beyond the payment.
3. Find the right used car and seller
Compare candidates on model year, trim, mileage, condition, and service history — then weigh them against how you will actually use the car. Before you spend time on a listing, check for known problems in that model year; our years-to-avoid research flags model years with recurring complaints.
Dealer or private seller is a real trade-off. A dealer handles financing and paperwork and, for used cars, must post an FTC Buyers Guide on the window. A private seller is often cheaper, but you handle the title transfer and any lien payoff yourself. And be precise about “certified”: a manufacturer CPO program and a dealer’s own in-house “certification” are not the same coverage — confirm who actually backs it.
When you are ready to see what is on the market, search used inventory near you.
4. Ask the seller the right questions
A short list of direct questions filters out most bad listings before you drive anywhere. Adjust for who you are buying from — the title and lien questions matter most with a private seller; the certification and return questions matter most at a dealer.
- Is the vehicle still available, and can you send the VIN?
- What is the complete written price, including any conditions on the advertised price?
- Private seller: are you the titled owner (or legally authorized to sell), and is there an outstanding loan?
- Are there any known collisions, flood exposure, title brands, or major repairs?
- Which maintenance records and inspection reports can I review?
- Are any warning lights on, and have there been recent diagnostic repairs?
- Will you allow an independent inspection, including a mobile inspection if needed?
- What work is due soon, and are both keys and any charging accessories included?
- For a certified car: who provides the certification and warranty, and what are the exclusions and deductibles?
- What warranty and return terms will appear in the signed paperwork?
5. Check the VIN, title, history, and recalls
Each check establishes something different, and each has limits. Start by decoding the VIN and confirming it matches the car and the paperwork — our VIN decoder identifies the specs, but a decode does not prove a clean history.
| Check | What it establishes | What it can miss |
|---|---|---|
| VIN decode | Year, trim, engine, factory equipment | Accidents, title brands, real condition |
| History report | Reported accidents, ownership, service records | Unreported damage; coverage varies by provider |
| Title / brand check | Salvage, rebuilt, flood, or lemon brands | Damage that was never titled |
| Recall lookup | Open safety recalls for that VIN | Non-safety issues; stated coverage limits |
Look up open recalls directly at NHTSA’s recall tool and confirm any have been fixed. If a title looks branded, read what a branded title means before you go further. Title and loss-history databases like NMVTIS cover brands and reported events, not a complete repair history — the U.S. DOJ’s buyer-beware notice explains the scope.
6. Inspect and test-drive the car
Your own walk-around catches the obvious problems; an independent inspection catches the expensive ones. Look for rust, mismatched paint or uneven panel gaps (signs of repair), uneven tire wear, and any fluid leaks underneath. Inside, confirm every electronic works — windows, locks, climate control, infotainment, and warning lights.
The test drive
Drive on varied roads for long enough to reach highway speed. Brakes should feel firm with no grinding, steering should track straight, the transmission should shift smoothly, and no warning lights should appear once it is warm. A cleared trouble code or an incomplete readiness state is worth asking about — it is a reason to dig deeper, not by itself proof of fraud.
EV and hybrid checks
For an EV or hybrid, add battery health, the remaining battery warranty, and the charging hardware. Inspect the charging port and cable, run a short charging demonstration if you can, and confirm the car fits your charging setup at home or work. Verify current manufacturer coverage directly — battery-warranty terms differ by brand and model year.
The most valuable step is an independent pre-purchase inspection by a mechanic you chose. Ask them for a written summary and a repair estimate; that estimate is real leverage in the next step. There is no single national inspection price — get a quote from the shop you pick.
Red flags that should pause a sale
- The seller won’t allow any independent inspection, even a mobile one.
- The VIN on the car, title, and paperwork don’t all match.
- A private seller isn’t the titled owner, or there’s an unresolved loan.
- Fresh undercoating or paint hiding areas you can’t inspect.
- Pressure to skip the inspection or wire a deposit before you’ve seen the car.
7. Decide what to offer and negotiate
Skip the “knock 10–20% off” rules of thumb. A defensible offer comes from genuinely comparable vehicles and the condition of the specific car, then adjusts for any repairs your inspection found. When you compare, be honest about what the numbers mean: an advertised listing is evidence of an asking price, not proof of what a car sold for.
| Vehicle | Mileage | Seller | Asking |
|---|---|---|---|
| 2021 Model, EX trimClean history, one owner; certified — confirm who backs the warranty. | 38,000 mi | Franchise dealer | $22,900 |
| 2021 Model, EX trimHigher mileage, no certification; records available. Priced for the mileage. | 52,000 mi | Private seller | $20,400 |
| 2020 Model, LX trimOlder year, lower trim; one reported minor accident. Not a true match for the EX cars. | 41,000 mi | Independent dealer | $19,800 |
The private-seller car looks cheapest, but its extra 14,000 miles and missing certification explain the gap — it may not be the better deal once you price the warranty and near-term maintenance. The 2020 LX is a different trim and year, so it is not a clean comparable at all.
Put your counteroffer in writing and tie it to specifics: “Based on comparable EX cars around $22,900 and the $600 in front brakes your inspection flagged, I can do $21,500 out the door.” If you have a written quote already, you can have CarWhere analyze it and check the math and fees before you respond.

8. Review fees, warranty, and return terms
Get the full out-the-door quote in writing and read every line. Separate the charges you can’t change — sales tax, title, and registration — from dealer-controlled ones like the doc fee, add-ons, and “protection packages.” Our dealer-fee guide breaks down which fees are legitimate and which are pure profit.
Optional products — extended service contracts, gap insurance, paint or fabric protection — are negotiable and often marked up; price them separately and decline what you don’t want. Read any warranty’s exclusions and deductibles. And don’t assume you can return the car: there is no universal federal three-day right to cancel a dealer car purchase. Some states and some dealers offer limited returns, but only the written terms count — the FTC’s used-car guidance explains what a dealer’s promises do and don’t cover.
9. Pay and complete the paperwork
Before money changes hands, confirm the seller’s authority to sell, that any lien is being paid off, and that the VIN is consistent across the title and every document. Finalize your financing and insurance so the car is covered the moment you drive it.
Title transfer and registration rules are set by your state, so the exact forms, fees, and deadlines vary — check your state’s requirements rather than assuming a single national rule. With a private sale, you and the seller complete the title assignment and, if there was a loan, confirm the lienholder releases it. Keep copies of the signed quote, the title, and the bill of sale.
10. After you buy
Finish the registration steps for your state and keep your purchase records together. Schedule the maintenance the inspection flagged, re-check open recalls periodically, and start a simple service log. If the car has connected-car features, remove the previous owner’s account access and set up your own. New to all of this? Our first-time car buyer guide covers the fundamentals in more depth.

Frequently asked questions
What should I check when buying a used car?
Decode and match the VIN, pull a title and history report, and look up open recalls at NHTSA. Inspect the body for rust and repaint, confirm every electronic works, and test-drive on varied roads. Then get an independent pre-purchase inspection and a written repair estimate before you agree on a price. No single check is complete on its own — a history report can miss unreported damage, so pair it with an inspection.
How much can you negotiate on a used car?
There is no universal percentage. A defensible offer is built from comparable vehicles (same year, trim, mileage, and condition), the written charges on the quote, and any repairs an inspection turns up — not a fixed “10–20% off.” A car that has sat on the lot for weeks, or one that needs work, gives you more room; a well-priced, in-demand car gives you less.
Is it better to buy from a dealer or a private seller?
Each has trade-offs. Dealers handle financing and paperwork and, for used cars, must post an FTC Buyers Guide; a private seller is often cheaper but you manage the title transfer and lien payoff yourself. “Certified pre-owned” only means something if you confirm who backs the certification — a manufacturer program and a dealer’s in-house “certification” are not the same coverage.
Does a vehicle history report catch every problem?
No. History reports draw on reported data, so unreported accidents, flood damage, or odometer issues can slip through, and coverage varies by provider. Use one to screen for title brands and reported events, then confirm the car independently with a VIN decode, an open-recall check at NHTSA, and a mechanic’s inspection.
Do I get a three-day right to return a used car?
Usually not. There is no universal federal three-day “cooling-off” right for a car you bought from a dealer. Some states grant limited rights and some dealers offer their own return policy, but you have to confirm the actual written terms before you sign. Do not assume you can return it.
Can I use the same process for a certified or EV used car?
Yes, with extra checks. For CPO, verify the actual program, warranty provider, and exclusions. For an EV or hybrid, add battery health, remaining battery warranty, charging-port and cable checks, and whether it fits your charging setup. Confirm current manufacturer coverage directly rather than relying on the listing.
