Where to search for used cars depends on what you want to buy and how much work you're willing to do

The biggest used car marketplaces — Autotrader, Cars.com, and Craigslist — let you filter by price, mileage, location, and features, then contact sellers directly. Dealership websites and manufacturer certified pre-owned (CPO) programs show inventory with dealer support built in. Facebook Marketplace and local classifieds reach private sellers who may not list elsewhere. Each route has different protections, pricing, and the amount of legwork you'll handle yourself.

Your choice depends on three things: whether you want a dealer's warranty and return window, how much time you have to inspect and negotiate, and whether you're comfortable meeting strangers or prefer a business transaction. A dealer costs more but handles paperwork and often provides a short warranty. A private seller costs less but puts the inspection and title transfer on you.

Key Takeaways

  • National sites like Autotrader and Cars.com show inventory from both dealers and private sellers, with filters for price, mileage, and features that narrow results fast.
  • Dealership websites and certified pre-owned programs add warranty coverage and return periods, but prices run higher than private-party sales.
  • Private sellers on Craigslist and Facebook Marketplace offer lower prices but require you to inspect the car, verify the title, and handle the sale yourself.
  • Always get a pre-purchase inspection from an independent mechanic before handing over money, regardless of where you find the car.
  • Check the vehicle history report (Carfax or AutoCheck) to see accident records, title status, and service history before you contact the seller.

National marketplaces: Autotrader, Cars.com, and Edmunds

Autotrader and Cars.com are the largest used car search engines in the United States. Both let you search by make, model, year, price range, mileage, and features. You can filter by distance from your zip code, see dealer inventory and private listings side by side, and contact sellers through the site. Edmunds works similarly but also includes pricing data and user reviews for each model.

These sites don't sell cars themselves — they're listing services. Dealers and private sellers post inventory, and you reach out directly. Response time varies: dealers usually reply within hours, private sellers may take a day or longer. You can save searches and get alerts when new cars matching your criteria are posted, which is useful if you're looking for something specific like a particular year and color.

The downside is volume. A search for "Honda Civic under $15,000 within 50 miles" might return hundreds of results. You'll need to narrow by year, mileage, or features to make the list manageable. Read the full listing and photos carefully — some private sellers post minimal details, and some dealers list cars that have already sold.

Dealership websites and certified pre-owned programs

Most car dealerships have their own websites showing current inventory. Manufacturer certified pre-owned (CPO) programs — like Toyota Certified, Ford Certified, or Honda Certified — are dealership inventory that meets the manufacturer's standards for age, mileage, and condition. CPO cars come with an extended warranty (usually 6 years or 100,000 miles, though terms vary by brand) and a return period of 3 to 7 days in most cases.

Buying from a dealership means you get a title transfer handled by the dealer, a warranty, and recourse if something goes wrong when ready after purchase. The trade-off is price: the same car costs $1,000 to $3,000 more from a dealership than from a private seller, and you have less room to negotiate because the dealer has already priced in their margin and the warranty cost.

Search dealership sites directly by brand, or use Autotrader and Cars.com to filter results to show only dealer inventory. If you're interested in a specific model, visit the manufacturer's website — most have a "find a dealer" tool that shows CPO inventory at nearby locations.

Private sellers: Craigslist, Facebook Marketplace, and local classifieds

Craigslist and Facebook Marketplace connect you directly to private sellers in your area. Prices are typically $1,000 to $3,000 lower than dealer prices for the same car because there's no middleman and no warranty. You handle the inspection, negotiation, and paperwork yourself. Local newspaper classifieds and community bulletin boards still exist in some areas and work the same way.

The advantage is price and selection — you're seeing cars people are selling directly, not inventory a dealer has already marked up. The disadvantage is that you have no protection if the car has hidden problems. There's no return period, no warranty, and if the title is bad or the car has liens against it, you discover that after you've handed over money.

Safety matters here. Meet in a public place during daylight, bring someone with you, and never wire money or send a deposit before seeing the car in person. Scams exist on both platforms — sellers who take payment and disappear, or who sell a car with an outstanding loan that the lender can repossess.

How to narrow your search and compare results

Start with the basics: make, model, year range, and price ceiling. If you're flexible on year, searching a 5-year window (say, 2019–2024) gives you more options than a single year. Mileage matters less than maintenance — a well-maintained car with 100,000 miles can outlast a neglected one with 60,000 — but most buyers use it as a rough filter anyway.

Once you have a list, pull the vehicle history report for any car you're seriously considering. Carfax and AutoCheck both show accident history, title status, service records, and whether the car was a rental or fleet vehicle. A clean title and no major accidents are baseline. A history of regular oil changes and maintenance is a good sign. A salvage title, flood damage, or multiple accidents are red flags.

Compare the same car across different listings. If a 2020 Honda Civic with 50,000 miles is listed at $16,500 on one site and $13,900 on another, the cheaper one may have higher mileage, accident history, or a less desirable color. Check the details before assuming one seller is just cheaper.

Getting a pre-purchase inspection before you buy

Before you hand over money to anyone — dealer or private seller — take the car to an independent mechanic for a pre-purchase inspection. This is not the dealer's inspection or the seller's word that the car is fine. You pay a mechanic (usually $100 to $200) to spend an hour checking the engine, transmission, brakes, suspension, and electrical systems.

The inspection report tells you what repairs the car needs now and what might need attention in the next year or two. A car with a clean inspection and recent brake pads is different from one that needs a transmission fluid flush and new tires. This information changes what you should pay and whether you want the car at all.

Most private sellers will let you take the car to a mechanic before you commit. Some dealerships include a pre-purchase inspection in their CPO warranty, but you can still request an independent inspection if you want a second opinion. If a seller refuses to let you inspect the car, walk away — that's a sign they know something is wrong.

Negotiating price and handling the sale

Dealer prices are usually firm, especially on CPO cars with warranty coverage. You can negotiate on non-CPO dealer inventory, but expect less movement than with a private seller. Private sellers almost always expect negotiation — if they list a car at $14,000, they may accept $13,200.

Use the vehicle history report, inspection report, and comparable listings to justify your offer. "The Carfax shows an accident, and the mechanic found $800 in needed repairs" is a concrete reason to ask for a lower price. "I found the same car cheaper elsewhere" is also valid — if you have a screenshot of the other listing, show it.

Once you agree on a price, get the agreement in writing. For a private sale, a bill of sale with the seller's name, your name, the car's VIN, the sale price, and the date protects both of you. For a dealer, they'll provide the paperwork. Before you leave with the car, confirm the seller has the title in hand and it's free of liens. If the seller says they'll mail the title later, do not take the car.

Frequently Asked Questions

Should I buy from a dealer or a private seller?

Dealers cost more but handle paperwork and provide a warranty. Private sellers cost less but require you to inspect the car and manage the title transfer yourself. Choose based on your budget and comfort level with the process. If you want peace of mind and don't mind paying extra, a dealer or CPO program is simpler. If you're confident inspecting a car and want the lowest price, a private seller works.

What's the difference between Carfax and AutoCheck?

Both show accident history, title status, and service records, but they pull from different databases. Carfax is more widely used, but AutoCheck sometimes catches accidents Carfax misses. Buying both reports for a car you're seriously considering costs about $40 total and gives you the most complete picture.

Can I negotiate the price on a certified pre-owned car?

CPO prices are usually set and firm because the manufacturer's warranty is built into the cost. You have more negotiating room on non-CPO dealer inventory and significantly more with private sellers. Always ask — the worst they say is no — but expect less movement on CPO cars than elsewhere.

What should I do if I find a car I like but it's far away?

Many dealers will ship a car to you or hold it while you arrange transport. Private sellers rarely ship. If the car is worth the cost of transport and you can have a mechanic inspect it before you commit, it may be worth pursuing. Get a pre-purchase inspection report from a local mechanic near the seller before you arrange payment or transport.

Is it safe to buy from someone on Craigslist or Facebook Marketplace?

Yes, if you take precautions. Meet in a public place during daylight, bring someone with you, and never send money before seeing the car. Have a mechanic inspect it before you pay. Verify the seller's identity and that the name on the title matches. If anything feels off, walk away — there are other cars.
