Carvana — Best for Fully Online Buying
Carvana lets you browse, finance, and buy a car entirely online, with home delivery or pickup from one of its vending-machine towers. Every vehicle goes through a multi-point inspection, and Carvana offers a short 7-day return window if the car isn’t what you expected.
Good for: buyers who want zero dealership visits and a fast, no-haggle process.
CarMax — Best for In-Person Support with Online Tools
CarMax combines a large physical presence (200+ locations) with online browsing and a no-haggle pricing policy. Its 10-day return window is longer than Carvana’s, which can matter if you want more time to decide.
Good for: buyers who want the convenience of online browsing but still want the option to visit a lot and get in-person support.
Autotrader — Best for Comparing Listings
Autotrader aggregates millions of listings from dealers nationwide, with filters for price, mileage, and features, plus a tool to compare up to five vehicles side by side.
Good for: buyers who want to see the widest possible selection and compare specs directly.
Cars.com — Best for Reviews and Research
Cars.com combines listings with owner and expert reviews for specific makes and models, which is useful if you’re still deciding what type of car you want, not just where to buy it.
Good for: buyers who want more research and community feedback before narrowing down a choice.
CarGurus — Best for Deal Ratings
CarGurus analyzes pricing data across thousands of listings and flags each one as a “Great Deal,” “Good Deal,” or “Fair Deal” based on market value — useful for quickly spotting overpriced listings.
Good for: buyers who want a quick gut-check on whether a specific listing is priced fairly.
KBB and Edmunds — Best for Valuation
Before buying from any of the platforms above, check Kelley Blue Book (KBB) or Edmunds to see the fair market value for the specific make, model, year, and mileage you’re considering. This gives you a benchmark to negotiate against or confirm you’re not overpaying.
How to Use These Sites Together
- Research value first on KBB or Edmunds so you know what a fair price looks like.
- Browse broadly on Autotrader or CarGurus to see what’s available in your area.
- Check reviews on Cars.com for the specific make and model you’re leaning toward.
- Buy online through Carvana or CarMax if you want a no-haggle, delivery-based purchase — or use the research above to negotiate confidently at a traditional dealership.
Frequently Asked Questions
Is it safe to buy a used car entirely online?
Yes, from established platforms like Carvana and CarMax — both offer vehicle history reports, inspection guarantees, and return windows that reduce the risk compared to a private sale.
Do these websites offer financing?
Most do. Carvana, CarMax, and Autotrader all let you get pre-qualified or apply for financing directly on their site before you commit to a specific vehicle.
Which site has the lowest prices?
No single platform is consistently cheapest — prices vary by listing. Checking KBB or Edmunds for a fair market value first is more reliable than assuming any one site is always the best deal.
What’s the difference between CarMax and Carvana?
CarMax has physical locations you can visit and a longer 10-day return window; Carvana is fully online with home delivery and a shorter 7-day return window.
