What car purchase sites do and which ones to use

Car purchase sites fall into three categories: dealer inventory sites (where franchised dealerships list their stock), marketplace sites (where private sellers and dealers both post), and manufacturer direct sites (where you configure and order from the factory). Each type shows you different inventory, charges different fees, and connects you to different sellers. Knowing which category fits what you're looking for saves time and money.

The largest dealer inventory sites are Autotrader, Cars.com, and Edmunds. These aggregate listings from thousands of franchised dealerships across the country. Facebook Marketplace and Craigslist are the main platforms for private sellers. Carvana, Vroom, and Shift are online-only retailers that buy used cars, inspect them, and sell them directly to you. Manufacturer sites like Tesla.com, Ford.com, and Chevrolet.com let you build a new car and order it, though most still route you through a local dealer for delivery and service.

Key Takeaways

  • Dealer inventory sites like Autotrader and Cars.com show stock from franchised dealerships but do not sell the cars themselves — you negotiate with the dealer.
  • Online-only retailers like Carvana and Vroom handle the entire transaction online, including delivery, but typically charge higher prices than traditional dealers.
  • Private seller sites like Facebook Marketplace and Craigslist have no middleman fees but require you to inspect the car yourself and handle your own financing.
  • Manufacturer sites let you configure a new car and order it, but most still require you to complete the purchase through a franchised dealer in your area.
  • Each site type charges different fees, offers different return windows, and gives you different protections — comparing across categories matters more than comparing within one.

Dealer inventory sites: Autotrader, Cars.com, and Edmunds

These three sites are search engines for dealership inventory. They do not own the cars or handle the sale — they show you what's available at franchised dealerships near you, let you filter by price, mileage, and features, and connect you to the dealer's sales team. The dealer pays the site a listing fee, not you.

Autotrader and Cars.com are the largest and have the most inventory. Edmunds includes pricing data and owner reviews alongside listings. All three let you message dealers directly through the site or call them. The dealer then negotiates price, arranges financing through their lender or yours, and handles the paperwork. You visit the dealership to inspect the car and sign documents.

The advantage is selection — you can see hundreds of cars across multiple dealerships without leaving home. The disadvantage is that you're still buying from a traditional dealership, which means negotiating, dealer markups, and the dealership's financing offers (which are often more expensive than a bank loan you bring yourself). Return windows vary by dealer and state, typically 3 to 7 days.

Online-only retailers: Carvana, Vroom, and Shift

These companies buy used cars at auction, inspect and recondition them, photograph them, and sell them directly to you online. You browse their inventory, choose a car, complete the purchase and financing online, and they deliver it to your home or a local pickup location. You never visit a physical lot.

Carvana and Vroom are the largest. Both offer 7-day return windows and handle all paperwork digitally. Shift operates in fewer states but offers similar terms. All three arrange financing through their own lenders or let you bring your own. Delivery is usually included or costs a flat fee.

The trade-off is price. Online-only retailers typically charge 10 to 20 percent more than a comparable car at a traditional dealership because they have higher overhead (customer service, delivery, reconditioning) and lower volume. You also cannot negotiate price — the price on the site is the price you pay. The advantage is convenience: no dealership visit, no negotiation, and a clear return window. If you value time and simplicity over the lowest possible price, this route works.

Private seller sites: Facebook Marketplace and Craigslist

These are classified ad platforms where individuals list cars for sale. You search, contact the seller directly, inspect the car in person, and negotiate price. You arrange your own financing (bank loan or cash) and handle the title transfer yourself or through a title service.

The advantage is price — private sellers typically ask less than dealers because they have no overhead. You also have room to negotiate. The disadvantage is risk: there is no inspection may provide, no return window, and no recourse if something breaks the day after you buy it. You are responsible for getting a pre-purchase inspection from a mechanic you choose, which costs $100 to $200 but is essential.

Craigslist has been the standard for years but has become less active in many regions. Facebook Marketplace has grown significantly and integrates with your Facebook account, which provides some seller history. Both require you to meet the seller in person, bring cash or arrange a bank transfer, and handle all paperwork yourself. Title transfer rules vary by state — some states let you do it online, others require an in-person visit to the DMV.

Manufacturer sites: Tesla, Ford, Chevrolet, and others

Most car manufacturers let you configure a new car on their website — choose the model, color, interior, wheels, and options — and place an order. You then either pick it up at a local dealership or have it delivered. Some manufacturers, like Tesla, handle the entire transaction online. Others, like Ford and General Motors, route you through a franchised dealer for final paperwork and service.

The advantage is that you get exactly the car you want, built to your specifications, rather than choosing from existing inventory. You also avoid negotiating with a dealer. The disadvantage is wait time — custom orders typically take 8 to 12 weeks. You also cannot see or test-drive the car before you buy it, though most manufacturers offer a short return window (typically 3 to 7 days) if you change your mind after delivery.

Pricing on manufacturer sites is usually fixed — no negotiation — and you see the full breakdown of costs upfront. Financing is arranged through the manufacturer's captive lender or a bank of your choice. If you know exactly what you want and can wait, this route removes uncertainty and negotiation.

Comparing fees, protections, and return windows

Each site type has different costs and protections built in. Dealer inventory sites charge you nothing — the dealer pays the listing fee. Online-only retailers charge you the full retail price, which includes their overhead. Private sellers charge whatever you negotiate. Manufacturer sites charge the manufacturer's suggested retail price (MSRP) with no negotiation.

Return windows vary significantly. Online-only retailers offer 7 days. Traditional dealerships offer 3 to 7 days depending on state law and the dealer's policy. Private sellers offer nothing — the sale is final. Manufacturer sites typically offer 3 to 7 days. Some states have "cooling-off" laws that give you a few days to cancel any car purchase, but not all do.

Financing protections also differ. Dealer inventory sites and manufacturer sites let you bring your own bank loan, which is usually cheaper than dealer financing. Online-only retailers and private sellers also let you bring your own financing. If you use the seller's financing, read the terms carefully — dealer financing often includes add-ons like extended warranties and gap insurance that increase the total cost.

How to choose the right site for your situation

Start by deciding what matters most: price, selection, convenience, or certainty. If price is your priority, search private seller sites first, then dealer inventory sites, then online-only retailers. If you want the widest selection, use dealer inventory sites. If you want the fastest, simplest transaction, use online-only retailers. If you want a specific new car, use the manufacturer site.

Next, decide whether you want to negotiate. Dealer inventory sites and private seller sites require negotiation. Online-only retailers and manufacturer sites have fixed prices. If you dislike negotiating, the latter two save time and stress.

Finally, consider your timeline. Private sellers and dealer inventory sites have when ready inventory. Online-only retailers have inventory but may not have your exact car. Manufacturer sites require you to wait for a custom build. If you need a car quickly, dealer inventory sites are fastest.

Frequently Asked Questions

Can I negotiate price on Autotrader or Cars.com?

You negotiate with the dealership, not the website. The price listed is the dealer's asking price, not the final price. Contact the dealer through the site or by phone and make an offer. Dealers expect negotiation, especially on used cars.

Is it safe to buy from a private seller on Facebook Marketplace?

It is as safe as any private transaction if you take precautions: meet in a public place, bring someone with you, get a pre-purchase inspection from a mechanic, and verify the title is clean before you hand over money. Use a bank transfer or cashier's check rather than cash if possible, so there is a record.

What happens if I order a car from Tesla.com and hate it when it arrives?

Tesla offers a 7-day return window. You can return the car for a refund if you change your mind, though you are responsible for return shipping costs. Other manufacturers have similar windows — check the specific policy before you order.

Do online-only retailers like Carvana inspect the cars they sell?

Yes, they inspect and recondition every car before listing it. However, their inspection is their own — it is not a third-party certification. If you want an independent assessment, you can still have a mechanic inspect the car during the return window before you decide to keep it.

Can I use my own financing if I buy from a dealership through Autotrader?

Yes. You can bring a pre-approved loan from your bank or credit union. The dealer will still offer their own financing, but you are not required to use it. Bringing your own financing often saves money because dealer financing includes their markup.
