The best place to buy used cars depends on how much risk you want to carry yourself. For a return window and a fixed price, start at CarMax or Carvana. For a factory-backed warranty, shop a franchise dealer’s certified pre-owned stock. For the lowest price, if you can arrange your own inspection, a private seller wins. Below: where to shop, what to verify before you sign, and the federal paperwork that protects you.

Which Channel Fits Your Needs?
A used car is any vehicle sold after its first retail owner, from a one-year-old lease return to a fifteen-year-old commuter with a rebuilt title. The second owner skips the steepest part of the value drop. What you give up is certainty, and each channel sells a different amount of it back.
| Channel | Price level | Buyer protection | Your effort |
|---|---|---|---|
| No-haggle superstore | Highest | Short return window, limited warranty | Low |
| Franchise dealer CPO | High | Factory-backed warranty extension | Low |
| Online retailer | Mid to high | Return window, bought sight-unseen | Low |
| Independent lot | Mid to low | Often as-is, per the Buyers Guide | Medium |
| Private seller | Lowest | None, sold as-is | Highest |
- First-time buyer on a tight budget: a superstore or online retailer costs more but lets you undo a bad choice.
- Keeping it past five years: factory CPO coverage on a reliable model is usually the right price for peace of mind.
- You know a mechanic and hold cash or a pre-approved loan: private party and independent lots leave the most room to negotiate.
Return Windows at the Big Retailers (Checked October 2026)
Only two national retailers publish a money-back guarantee, and one of them has shortened it. CarMax cut its guarantee from 30 days to 10 days for purchases made on or after May 12, 2024, according to Automotive News and Kelley Blue Book coverage of the change. Carvana still offers a 7-day money-back guarantee that starts the day you take delivery, with a mileage cap during that week. Many pages still quote the old 30-day, 1,500-mile CarMax terms, so read the policy in your paperwork.
| Seller | Return window | Practical note |
|---|---|---|
| CarMax | 10 days | Reduced from 30 days in May 2024; return as sold |
| Carvana | 7 days from delivery | Mileage cap applies, so book your mechanic early |
| Franchise dealer CPO | Varies by brand and store | Ask for the policy in writing |
| Independent lot | Usually none | Final once the Buyers Guide says as-is |
| Private seller | None | As-is, no FTC Buyers Guide required |
Ten days is enough for one independent inspection if you book it before pickup. A marketplace listing works differently: the selling dealership owns that deal, so the site brand gives you no return rights.
Buying Used Cars Online: Who Still Sells
Four online channels carry real inventory: Carvana, the CarMax storefront, and the marketplaces Autotrader and Cars.com. Two former names are gone. Vroom announced in January 2024 that it was winding down its ecommerce used vehicle business and finished that wind-down later in 2024, and Shift Technologies filed for Chapter 11 in October 2023 to close its operations. Any guide still pointing you to either is stale.
Carvana
Carvana sells entirely online with home delivery across most United States metros. Since you never test drive first, the 7-day guarantee is your test: take delivery, drive it, hand it to your mechanic, and send it back if anything looks wrong. Browse their listings.
CarMax
CarMax runs a hybrid model: more than 200 stores nationwide plus online ordering and home delivery in many markets. Every listing carries a no-haggle price and a free history report. Nationwide transfer moves stock between stores, though timing and any transfer fee depend on distance. See their search page.
Autotrader and Cars.com
Both are marketplaces, not sellers. They aggregate dealership and private party inventory nationally, let you filter by price, mileage, trim, and distance, then hand you to the seller. They are the fastest way to shop for used cars across many sellers once you know the exact model you want. Search their listings page or the Cars.com search.
Local Lots, Fleet Sales, and Private Sellers
Shopping locally wins on the one thing the internet cannot match: you drive it before you own it.
Franchise dealerships and certified pre-owned
A franchise car dealership sells one manufacturer’s new inventory plus trade-ins, and its certified pre-owned program is the only certification backed by the factory. CPO stock costs more than equivalent non-certified stock on the same lot in exchange for a warranty extension, a brand inspection checklist, and roadside assistance. Toyota’s program page shows what to compare.
Independent lots and rental fleet sales
Independent lots handle older, higher-mileage stock at lower prices with thinner protection, and most sales are as-is. Retail programs from Hertz and Enterprise sit in between: late-model vehicles with one corporate owner and documented service, priced below a franchise store.
Private sellers and auctions
Private listings on Facebook Marketplace and Craigslist carry the lowest prices and zero protection. Pay with a cashier’s check from your bank and swap it for the signed title in person; a money order works only for a deposit, since the U.S. Postal Service caps each domestic money order at 1,000 USD. Auctions differ again. Copart and Manheim move wholesale and salvage inventory mostly to licensed dealers, though some public sales admit retail buyers. Treat auction stock as a project unless you inspect it in person, and budget for car parts before you bid.
The Federal Paper Trail: Buyers Guide, Recalls, and Title Records
Three federal records protect you better than any sales promise, and each covers a gap the others miss.
The Buyers Guide. The Federal Trade Commission Used Car Rule requires dealers to post a Buyers Guide on every used car they offer, stating whether it is sold as-is or with a warranty. The part most buyers misread: the FTC says the Buyers Guide overrides the sales contract, so any warranty you negotiate must be written onto the Guide itself. If the “As Is” box is ticked, every repair after the sale is yours. Private sellers are not covered by the rule.
The CARS Rule is gone. The FTC’s separate Combating Auto Retail Scams (CARS) Rule, aimed at junk add-on fees and bait pricing, was vacated by the Fifth Circuit Court of Appeals on January 27, 2025, before it took effect. The Used Car Rule was not affected. No federal rule now requires an all-in price up front, so ask for one.
Open recalls. Run the 17-character VIN through the free lookup at the National Highway Traffic Safety Administration, the federal agency that oversees vehicle safety. The reason this check matters on a used lot: federal law bars dealers from selling new vehicles with open safety recalls, but no equivalent federal ban covers used ones. A franchise dealer for that brand performs recall repairs at no charge regardless of who owns it.
Title history from NMVTIS. The National Motor Vehicle Title Information System is a Department of Justice database of title brands, odometer readings, and salvage and total-loss records. Consumers buy NMVTIS reports through the approved data providers. It catches title washing, where a flood or salvage brand from one state disappears after a retitle in another.
What to Check on the Vehicle Itself
Paper tells you what was reported. The car tells you what happened.
Vehicle history report. Carfax is a vehicle history database that pulls title records, reported accidents, odometer readings, and service entries against the VIN. AutoCheck runs the same idea on a different network. A branded title is disqualifying and cheap to spot, but these reports only list what was reported, so cash-paid body work often never appears.
Independent inspection. A pre-purchase inspection by a mechanic who does not work for the seller finds what no paperwork shows: fluid leaks, frame rust, worn rotors, stored fault codes. The FTC recommends one even on certified cars and suggests taking a dealer’s refusal as a reason to shop elsewhere. Ask for a written report with repair estimates; it doubles as a bargaining tool.
Model track record. Toyota and Lexus have sat at or near the top of Consumer Reports brand reliability rankings for years, part of why a Toyota Camry, Toyota RAV4, Toyota Highlander, or Toyota Tacoma holds price.
Battery health on anything electrified. On a hybrid or EV the traction battery is the priciest component, and its capacity never appears on a window sticker. Ask for a state-of-health readout and confirm how much of the manufacturer’s battery warranty is left; 8 years or 100,000 miles is common, and some states require longer.
Title status and records. Clean, salvage, rebuilt, flood, and manufacturer buyback titles are five products at five values, and lenders and insurers treat branded titles differently. On a private sale, a folder of receipts proving the timing belt and transmission service were done is the most underrated signal you will find.
Financing: Get Pre-Approved Before Anyone Quotes a Payment
The most expensive habit in a dealership is negotiating a monthly payment instead of a purchase price. A longer term makes almost anything fit the budget while raising the total you pay; the FTC advises comparing APR, term, and total cost.
Get a pre-approval first. The Consumer Financial Protection Bureau’s auto loan tools explain how to shop for a loan from a bank or credit union first, so the finance office has a rate to beat. Then settle the out-the-door number, including documentation fee, title, and registration. Some states cap that doc fee by statute while others leave it open.
Finance-office add-ons come last: service contracts, gap coverage, paint sealant. Price each separately or decline it. Gap coverage is often cheaper from your own insurer, and a service contract is not a warranty.
Best Places to Buy Used Cars Right Now
These five cover every buyer profile, ranked by protection relative to price.
Best overall: CarMax. Deep nationwide inventory, one fixed price, and a 10-day money-back guarantee. Pro: you can test drive first. Con: fixed pricing sits above private party at the same year and mileage. See current stock
Best online: Carvana. The whole purchase happens on a phone, and the 7-day window leaves time for a real inspection. Pro: no dealership visit. Con: you commit before driving it. See current stock
Best long-term value: franchise dealer certified pre-owned. A factory-backed warranty extension on a unit that passed the manufacturer’s own inspection. Pro: the only certification that means something specific. Con: it rarely pays off on a short hold. Compare one brand’s terms
Best selection: Autotrader. National aggregation of dealership and private party inventory with deep filters for trim, mileage, and distance. Pro: it finds rare configurations. Con: it is a search engine, not a seller. Run a search
Best for private party: Cars.com. Private listings sit alongside dealership stock. Pro: the lowest prices here. Con: as-is every time, so budget for an inspection and basic tools. Browse private listings
Whichever channel you choose, run the same sequence.
- Pull the history report. Enter the VIN on Carfax, AutoCheck, or an NMVTIS provider so a branded title or odometer gap surfaces early.
- Look up open recalls. The NHTSA lookup is free, takes the same VIN, and an unrepaired recall is a bargaining point.
- Set a market value. Kelley Blue Book and Edmunds give you trade-in, private party, and dealer retail values before anyone quotes a number.
- Get a pre-approval. An auto loan offer from your own bank or credit union gives the finance office something to beat.
- Book an independent inspection. Pay a mechanic who does not work for the seller, before any money moves or inside the return window.
- Negotiate the out-the-door total. Settle documentation, title, and registration in one number, then talk financing.
Start with step one tonight: pull a history report and a recall check on the two used cars you like best, then book the inspection before you visit. If a seller stalls on the inspection, walk. For a stored or seasonal vehicle, ethanol-free gas and a fresh battery are worth sorting out once it is yours; our automotive buying guides cover the rest.
Questions Buyers Ask Before Signing
Should I buy a used car with over 100,000 miles?
Yes, if the maintenance history supports it and the model has a reputation for durability. Six figures on the odometer is no longer the wall it was twenty years ago. What matters more is whether the expensive interval work was done, particularly a timing belt, since that job alone can run four figures.
What is the difference between manufacturer CPO and a dealer’s own “certified” label?
Manufacturer certified pre-owned is backed by the automaker and honored at any franchise store for that brand nationwide. An in-house “certified” sticker is backed only by the lot that applied it, and usually means a third-party service contract. Ask for the warranty document, not the brochure.
Is a Carfax report worth paying for?
On a private party purchase, yes, because nobody else is paying for one. These files contain only what was reported to insurers, police, or shops in the network, so collision work paid in cash frequently never appears. Treat a clean one as necessary but not sufficient, and pair it with an NMVTIS title check.
Can a dealer sell a used car with an open recall?
Yes. Federal law prohibits selling new vehicles with open safety recalls, but it does not extend that ban to used ones sold by dealers. Check the VIN on the NHTSA lookup yourself, and ask the seller to complete the free recall repair before delivery.
Can you lease a pre-owned vehicle, or buy one with nothing down?
Pre-owned leasing exists but is uncommon, and stores that offer it usually restrict it to low-mileage certified stock a few years old. Zero-down financing is far easier to find. The catch is negative equity: you owe more than the vehicle is worth the moment you drive away.
Can I trade in my current vehicle when buying used cars?
Yes, and in most states the trade-in reduces the taxable amount of the purchase, so you pay sales tax only on the difference. Get a written offer from a superstore first, then use it as your floor when the dealership bids.
Retailer status, return policies, and federal rules were re-checked in October 2026 against company announcements, FTC guidance, and trade press. Confirm terms in writing before you buy.
