The main places to look for used cars

Used cars are sold through five main channels: dealerships that specialize in used vehicles, franchised new-car dealerships that also stock used inventory, private sellers, online marketplaces, and auction sites. Each has different protections, pricing, and what you can learn about the car's history before you buy. The best choice depends on whether you want convenience and some buyer protection, or whether you're willing to do more legwork to find a lower price.

Most people find used cars through a combination of these sources rather than stopping at the first one. You might start with online searches to see what's available and what prices look like, then visit dealerships or contact private sellers to inspect cars in person. Understanding what each source offers helps you spend your time on the places most likely to have what you need.

Key Takeaways

  • Used-car dealerships and franchised dealerships offer cars with some inspection history and return policies, but charge more than private sellers.
  • Private sellers typically price lower but offer no warranty or return option, so you need a pre-purchase inspection from a mechanic you choose.
  • Online marketplaces like Facebook Marketplace and Craigslist let you search by location and price, but require you to verify the seller and inspect the car yourself.
  • Auction sites and dealer auctions move cars quickly and sometimes have lower prices, but you may not be able to inspect before bidding.
  • Checking a car's history report through services like Carfax or AutoCheck costs $20 to $40 and reveals accidents, title problems, and service records.

Used-car dealerships and their protections

A used-car dealership buys vehicles wholesale, inspects them, and resells them with a markup. Most offer a short warranty (often 30 to 90 days on powertrain components like the engine and transmission) and a return period of a few days if you change your mind. Some dealerships are independent; others are part of larger chains. The trade-off is that you pay more than you would from a private seller—typically 10 to 20 percent higher—because the dealership's costs and profit are built into the price.

Before you buy from a used-car dealership, ask what warranty is included, whether it covers parts or labor, and whether you can take the car to any mechanic or only to the dealership. Request the service history and any inspection reports the dealership performed. A reputable dealership will have records showing what was checked and what repairs were made. You can also ask to have a mechanic of your choice inspect the car before you finalize the purchase, though some dealerships charge a fee for this or require it happen on their lot.

Franchised dealerships and certified pre-owned programs

Franchised dealerships (the ones that sell new cars from a brand like Toyota or Ford) also sell used vehicles, often including certified pre-owned (CPO) cars. A CPO car has been inspected to the manufacturer's standards, comes with an extended warranty (often three to seven years), and typically has lower mileage than other used cars. You pay a premium for this—usually 5 to 10 percent more than a non-certified used car of the same age and mileage—but the warranty and inspection history provide real protection.

The warranty on a CPO car is transferable, meaning if you sell the car later, the next owner keeps the remaining warranty. This can make CPO cars easier to resell. Franchised dealerships also have access to detailed service records from their own service departments, so you can see exactly what maintenance was done. If you're buying from a brand's dealership, ask whether the car was a trade-in, a lease return, or a rental—this history affects how hard the car was used.

Private sellers and what you need to check

Buying from a private seller usually means a lower price because there's no dealership markup. However, you get no warranty, no return period, and no inspection may provide. The seller is responsible for disclosing known problems, but enforcement depends on your state's lemon laws and whether you can prove the seller knew about a defect. This is why a pre-purchase inspection from a mechanic is essential when buying from a private seller—it's your only protection against buying a car with hidden problems.

Before meeting a private seller, ask for the vehicle history report (they may have one from Carfax or AutoCheck), service records, and the reason they're selling. When you meet, inspect the car in daylight, take it for a test drive, and listen for unusual noises. Ask the seller directly about accidents, repairs, and any recurring issues. Then take the car to a mechanic for a full inspection before you commit to buying. A pre-purchase inspection typically costs $100 to $200 and can reveal problems that would cost thousands to fix.

Online marketplaces and what to watch for

Facebook Marketplace, Craigslist, and Autotrader let you search for used cars by location, price, mileage, and model. These sites aggregate listings from both private sellers and dealerships, so you can compare options in one place. The advantage is speed and selection; the disadvantage is that you're responsible for verifying the seller is legitimate and that the car is as described. Scams do happen—sellers who take payment and disappear, or who misrepresent the car's condition or ownership status.

When using online marketplaces, meet the seller in a public place during daylight, bring someone with you, and never send money before seeing the car in person. Ask to see the title and verify the seller's name matches it. Request a vehicle history report and have a mechanic inspect the car before you buy. Be cautious of prices that seem too low for the model and mileage—this is often a sign of hidden problems or a scam. If a seller refuses to let you inspect the car or pressures you to decide quickly, move on.

Auction sites and how they work

Copart and IAA (Insurance Auto Auctions) sell vehicles that insurance companies have declared total losses, that banks have repossessed, or that rental companies are retiring. Prices can be significantly lower than retail, sometimes 30 to 50 percent below market value. However, most auction sites do not allow you to inspect the car before bidding, and you typically cannot return it after purchase. Cars are sold "as-is" with no warranty.

Auction sites require you to register and may charge a buyer's fee on top of the winning bid price. You also need to arrange transportation and insurance before you can drive the car away. Some auction cars have minor cosmetic damage; others have structural or mechanical problems that aren't visible in photos. If you use an auction site, review all available photos and descriptions carefully, bid conservatively, and factor in the cost of a post-purchase inspection and any repairs you discover. Auctions work best if you have mechanical knowledge or a trusted mechanic who can advise you on which cars are worth bidding on.

Comparing prices across sources

The same car model and year will have different prices depending on where you find it. A private seller might list a 2019 Honda Civic for $16,000, a used-car dealership might ask $18,500 for the same model with similar mileage, and a CPO version at a franchised Honda dealership might be $19,500. The price difference reflects the warranty, inspection, and return protections you get at each level. Before you decide where to buy, search multiple sources to see the range of prices for the car you want.

Use sites like Kelley Blue Book (KBB) or NADA Guides to see what a car should cost in your area based on mileage, condition, and options. These tools show you the typical retail price (what a dealership charges), the private party price (what a private seller typically asks), and the trade-in value (what a dealership pays you if you trade in your old car). Knowing these ranges helps you spot overpriced listings and negotiate confidently.

Frequently Asked Questions

Should I buy from a dealership or a private seller?

Dealerships offer warranties and return periods but charge more. Private sellers price lower but offer no protection. If you can afford a mechanic's inspection and are comfortable negotiating, a private seller saves money. If you want peace of mind and a safety net, a dealership or CPO car is worth the extra cost.

What is a vehicle history report and do I need one?

A vehicle history report (from Carfax or AutoCheck) shows accidents, title problems, service records, and whether the car was a rental or fleet vehicle. It costs $20 to $40 and is essential when buying from a private seller. Dealerships usually provide one, but you should still review it yourself before buying.

Can I negotiate the price at a used-car dealership?

Yes. Dealerships expect negotiation, especially on older or higher-mileage cars. Research the market price first, then make an offer 5 to 10 percent below the asking price. Be prepared to walk away if the dealership won't move—there are always other cars available.

What should I look for during a test drive?

Listen for unusual noises, check that the brakes feel responsive, test the steering and suspension on different road surfaces, and verify all electronics work (windows, locks, air conditioning, dashboard lights). If something feels off, have a mechanic inspect it before you buy. Never skip the test drive, even if the car looks perfect in photos.

Is it safe to buy from an online marketplace?

Yes, if you take precautions. Meet in a public place, bring someone with you, verify the seller's identity against the title, and never send money before inspecting the car. Have a mechanic inspect it before you buy, and always check a vehicle history report. These steps protect you from scams and hidden problems.
