Depends on how you sell it. That is the honest answer. A private sale can take a month. CarMax takes a day. Some options take 20 minutes.
I have been buying cars for over 30 years. More than 50,000 vehicles. I have seen every selling method from both sides. Here is what each one actually takes, with no sugarcoating.
The Quick Comparison
| Method | Time to Get Offer | Time to Get Paid | Your Effort | Typical Price vs. Private |
|---|---|---|---|---|
| Private Sale | 2-4 weeks | When buyer pays | 10-30 hours | 100% (the benchmark) |
| CarMax | 30 minutes | Same day | Drive there + wait | 82-86% |
| Carvana | Instant (online) | 3-7 days | Online form + pickup | ~90% (before inspection) |
| Dealer Trade-In | Same visit | Applied to purchase | Part of buying process | 70-80% |
| Mobile Dealer (at your home) | 20 minutes | Same visit | Be home | Matches CarMax or better |
Now let me break down what each method actually looks like day by day.
Private Sale: 2 to 4 Weeks (10-30 Hours of Work)
Private sale gets you the most money. That part is true. On a $20,000 car, you might get $2,800 to $3,600 more than CarMax would offer. The part people underestimate is what that costs in time.
Here is what a typical private sale looks like:
Days 1-2: Research your car's value on KBB and Edmunds. Wash and detail the car. Take 30-50 photos from every angle. Write a listing. Post on Facebook Marketplace, Craigslist, maybe OfferUp. This alone takes 4-6 hours if you do it right.
Days 3-7: The messages start. "Is it still available?" (yes, you just posted it). "Would you take $12K?" on your $18K listing. Scam texts within 24 hours. One Reddit user put it this way: "I got the same texts and emails with minor details changed from four different scammers, all with the same MO."
Days 7-14: You schedule test drives. People do not show up. One seller described it: "Twice I have had people say they are coming to view the car and they don't show up. Is it too much to send a text?" You rearrange your schedule, wash the car again, and wait.
Days 14-28: If you are lucky, you get a serious buyer. You negotiate. You handle the DMV paperwork. In California, that means title transfer, smog certification, release of liability, and odometer disclosure. If the buyer needs financing or the car has a lien, add more days.
The success rate tells the story. Reddit polls show that 60-85% of private sellers give up and end up going to CarMax or trading in at a dealer anyway. As one seller put it: "Week 3, 100 offers, 5 test drives, 0 sales. Traded to CarMax for 15% less but slept well."

CarMax: Same Day (30 Minutes to 2 Hours)
CarMax is the benchmark for speed and certainty. You drive in, they inspect your car for about 30 minutes, and you get a written offer valid for 7 days. If you accept, they write you a check or direct deposit within 48 hours. Most people walk out with payment the same day.
The catch is the price. CarMax typically offers 14-18% below private party value. On a $22,500 Honda Civic, that is about $3,300 less than you could theoretically get selling it yourself. On trucks, the gap is even wider: a 2018 F-150 worth $32,500 privately got a $27,200 CarMax offer in one documented case.
CarMax recently launched at-home pickup, so you do not even need to drive there anymore. But the price gap stays the same whether they come to you or you go to them.

Carvana: 3 to 7 Days
Carvana gives you an instant online offer based on the details you enter. That part takes 5 minutes. But getting paid takes 3 to 7 days because they need to schedule a pickup and complete an in-person inspection.
The problem is that the online offer is conditional. Carvana's own terms say the offer "can be adjusted downward during the physical inspection." Common reduction triggers include cosmetic damage you did not mention, dashboard warning lights, tire wear, and mileage driven since you got the quote. Reductions range from $200 to $3,000 or more.
One analysis noted: "Many sellers do not realize the offer can change until the inspector is standing in their driveway with a lower number."
Dealer Trade-In: Same Day (But You Are Buying Too)
If you are buying a new car, the trade-in happens as part of that transaction. The dealer appraises your car, applies the value as a credit, and you drive away in your new vehicle. Total time: whatever the buying process takes, usually 2-4 hours.
The downside is pricing. Dealer trade-ins are typically 20-30% below private party value. In extreme cases, the gap is even worse. One seller reported a $1,200 trade-in offer on a car they sold privately for $8,000.
The upside is simplicity. One transaction handles both selling and buying. And in some states, you only pay sales tax on the difference between the new car price and your trade-in value.
KBB Instant Cash Offer: 1 to 2 Days
Kelley Blue Book's Instant Cash Offer gives you an online estimate, then you visit a participating dealer within one day to get the final number. The "instant" part is the estimate. The actual offer comes after inspection, and it is at the dealer's discretion.
The offer is valid for 7 days, and the list of vehicles they will not buy is long: salvage titles, grey market vehicles, unresolved recalls, low-value cars, and vehicles with aftermarket equipment.
Why Private Sales Take Longer Than You Think
Most people think selling a car privately takes a weekend. The data says otherwise. Average time to sell a used car privately is 30 to 40 days. And that is the average for cars that actually sell. It does not count the ones that sit for months.
The time breakdown is not just listing and waiting. It is active work:
- Writing and rewriting listings: 2-4 hours
- Taking photos and editing: 2-3 hours
- Responding to inquiries and filtering scams: 5-10 hours over weeks
- Scheduling and rescheduling test drives: 3-5 hours
- Negotiating: 1-3 hours per serious buyer
- DMV paperwork (in California): 1-2 hours
Add it up and you are looking at 10 to 30 hours of effort spread across 2 to 6 weeks. If your time is worth $50 an hour, that "extra money" from private sale starts looking a lot smaller.

Which Method Is Right for You?
Choose private sale if: You have a popular car in great condition, you are not in a rush, and you are comfortable dealing with strangers, negotiations, and paperwork. You will get the most money, but you will earn it.
Choose CarMax or a dealer if: You want certainty and speed more than maximum price. You know you are leaving money on the table, but you value your time and peace of mind.
Choose a mobile dealer if: You want the speed of CarMax without driving anywhere, and you want to know that the price you are quoted is the price you get.
Most sellers start with private sale, get frustrated after 2-3 weeks, and end up at CarMax anyway. If you already know you do not want to deal with the hassle, skip ahead.
