The bottom line: The average franchised dealer made $1,399 gross on each used car it retailed in 2024, down on the year, by Presidio’s dealership benchmark. Reconditioning, transport and the lot come out of that before any profit is left, which is why a trade-in offer sits well below what a private buyer would pay for the same car.
Selling your car to a dealer or privately comes down to that margin. For a car in good shape, selling privately gets you the most money; a dealer will usually offer you less than a private buyer would pay, sometimes a lot less.
The gap narrows once you count your own time, the prep and, where your state gives one, the sales-tax credit on a trade-in. For a damaged or non-running car, junk buyers like Peddle and Wheelzy are often the only realistic option.
Before committing to any option, compare offers from multiple services with Sell Car Advisor to see the spread for your specific car.
Key Takeaways
- Dealer margin: a franchised dealer’s gross on a used car it resells is well under two thousand dollars by Presidio’s count, and its costs come out of that; your low trade-in offer is mostly reconditioning and overhead, not pure profit.
- Private sale: you’ll usually be offered more by a private buyer than by a dealer, sometimes a lot more, but your time, the prep and the trade-in tax credit eat into the premium.
- Sales tax: where your state gives a trade-in credit, the tax you save narrows the gap between the two routes; where it gives none, the private-sale premium is yours to keep.
and other online buyers usually offer more than a local dealer for the same car and skip the negotiation; the tax credit applies only if you buy from them in the same deal.
- Same-day quotes: two buyers looking at the same car are often hundreds of dollars apart in our data, so ask two or three on the same day before you accept any number.
- Waiting: an offer left to lapse usually comes back lower when you ask again, so line the quotes up in the same week.

What Dealers Actually Make on Your Car
Dealers price a used car above what they paid for it, but most of that gap goes toward reconditioning, transport and overhead rather than profit.
The profit per car is smaller than most sellers expect. The average franchised dealer’s gross on a used car it retailed was $1,399 in 2024, by Presidio’s dealership benchmark, against $2,247 on a new car.
The finance office made $1,581 per vehicle sold on top, which is where a good part of a dealer’s money now comes from, and why the used-car department can live on a thin gross.
The rest of the markup goes toward real costs. Here is an illustration of what a dealer spends on a car it acquires for $12,000; no publisher prices these lines, so read them as the shape of the costs, not a quote.
| Cost Item | Illustration | Notes |
|---|---|---|
| Acquisition price | $12,000 | Trade-in or auction cost |
| Auction fees and transport | $700 | Varies by source |
| State inspection | $80 | Required in most states |
| Reconditioning | $250 to $1,500 | Mechanical and cosmetic work |
| Detailing | $100 | Interior and exterior |
| Holding costs (lot) | $40 to $85 per day | Insurance, lot space, interest |
| Total before profit | ~$13,200 to $14,500 | Before any profit margin |
In the illustration, that $12,000 car costs the dealer $13,200 to $14,500 before a single dollar of profit is added. This is why they can’t offer you close to retail value as a trade-in.
The formula is straightforward: acquisition cost + reconditioning + overhead + profit = retail price. Your trade-in offer is essentially the acquisition cost they’re willing to pay, which is always the smallest number in that equation.
What the dealer resells is mostly younger stock; the figures below are what a three-year-old used car sells for and how long it sits, by Edmunds.
How the Dealer Margin Creates the Trade-In vs Private Sale Gap
The dealer margin explains a pricing order that holds for almost every used car. Take a car a dealer would list at retail.
A private buyer pays below retail. They’re getting no warranty, no reconditioning guarantee and no financing from you.
A dealer trade-in offer for that same car sits below the private buyer’s number. They need to cover all the costs in the table above and still turn a margin on the resale; the dealer trade-in guide covers what happens to your car once it’s theirs.
How wide the gap between the private price and the trade-in offer is depends on the car, and the only way to know yours is to get both numbers. That’s the raw margin difference before any other factors are considered.
The Real Private Sale Premium After Costs and Time
Private sales get you more money on paper. The gap between the raw numbers and what you actually net is smaller than it looks.
Creating listings, taking photos, answering calls, scheduling test drives, dealing with no-shows, and meeting potential buyers typically takes 8 to 16 hours. For someone earning $60,000 per year, 15 hours of your time is worth roughly $435.
Add prep costs on top of that:
- $100 to $200 on professional detailing
- $9.99 on a VinAudit vehicle history report to show buyers
- $100 to $500 on minor repairs buyers often request
A $2,000 advantage over a dealer trade-in can realistically shrink to around $1,300 in actual take-home, before the tax credit is even factored in.
How the Trade-In Tax Benefit Narrows the Gap Further
Depending on your state, trading in your car may reduce the taxable amount on your new car purchase. Where it does, the credit narrows the gap between trading in and selling privately.
- Without trade-in: You sell privately for $10,000 and buy a $30,000 car. You pay sales tax on the full $30,000.
- With trade-in: You apply your $10,000 as a trade-in credit. Where the credit applies, you pay sales tax on the $20,000 difference.
What that saves depends on your state’s rate. Combined with time and prep costs, the raw price advantage of a private sale can shrink to a few hundred dollars for someone buying another car at the same time.
Where your state gives no credit, you keep the full private-sale premium and have a stronger reason to skip the dealer trade-in. The guide below has the rule for every state.

Online Buyers: The Middle Ground
Online dealers like Carvana and CarMax usually offer more than a traditional local dealer for the same car. They carry the same trade-in tax credit as a dealership when you buy another car from them in the same transaction.
The tradeoff is that offers change quickly. In our data a car 10 years and older quoted again by the same buyer a month or more later was offered $40 less at the median, and 58% of them came back lower, with no change to the car.

An accident on the record costs too: in the same data a car that has been in one is offered about 10% less than a comparable car that hasn’t, and high mileage takes its own share off.

Special Situations: When the Margin Math Changes
Cars with Mechanical Issues
Private sales become much harder when a car has transmission or engine problems. Most private buyers walk away from major mechanical issues entirely.
Junk car buyers like Peddle and Wheelzy are often the best option here. They make an offer on a car a dealer may offer very little or nothing for.
The fault is priced, not refused: in our data a car 10 years and older that doesn’t start is offered about 47% less than the same car running, once age and mileage are matched.

High-Mileage Vehicles
At 150,000 miles, dealer interest drops quickly. Private buyers are more forgiving if you have service records. Online buyers tend to make much lower offers on cars with high mileage or a rough history.

Which Option Fits Your Situation
- Choose private sale when: You have 2 to 3 weeks, the car is in good condition, and you are not buying another car right away. The tax credit does not apply, so you keep the full premium.
- Choose dealer trade-in when: You are buying another car at the same time and your state offers the tax credit. The real difference after taxes and time often shrinks to a few hundred dollars.
- Choose an online buyer when: You want a fair price without the hassle of private sales, and your car is in good condition with reasonable mileage.
- Choose a junk buyer when: The car has major mechanical issues or won’t start. Private sales and dealer trade-ins are rarely realistic options in this case.
Action Steps: How to Maximize Your Sale Price
- Get multiple quotes on the same day: Offers from Carvana and local dealers change daily, and they disagree with each other. In our data the best and worst same-day offers on a car 10 years and older sit $328 apart at the median, and 44% of cars get one offer at least double another.
- Use KBB and Edmunds for baseline values: Know your trade-in value against your private party value before you talk to anyone; the KBB accuracy guide says how far each runs from a real offer.
- Get an online offer before visiting a dealership: Bring a written offer from Carvana or a similar buyer to use as a reference point.
- Check your state’s tax rules: Where the trade-in credit doesn’t apply, the math shifts in favor of a private sale; the trade-in tax guide above has the rule for every state.

How we got these numbers
The offer figures on this page come from 18,326 instant cash offers made to sellers from 2021 to 2026. They are offers from online car buyers, not sale prices, and we report the middle offer rather than the average, because a handful of very high offers would otherwise make a typical car look worth far more than it is.
The condition and offer-gap figures come from cars quoted by several buyers on the same day through our comparison tool, compared inside groups of the same age and mileage. Those same-day comparisons began in March 2026, so they cover the months since then, while the middle offer runs over every offer since 2021. The all-years middle offer stays because a short window holds a few hundred offers and moves with sampling; each chart prints the dates behind it. The full statistics and how each one is calculated.
Frequently Asked Questions
Do you get more money trading in a car or selling it to the dealer outright?
The offer is usually the same either way: it’s the dealer’s acquisition cost, whether the car goes against a purchase or is bought outright.
The difference is the sales-tax credit. Where your state gives one, it applies only when the trade-in and the new car are one transaction; sell the car to the dealer on its own and there is no credit.
Is it better to sell a 15-year-old car to a dealer or privately?
A dealer may offer little or nothing for a car that old, because it goes straight to auction rather than onto the lot. A private buyer will pay more if you can find one, but it takes time.
Online junk buyers quote a car like that in minutes. Across all our offers since 2021 the middle offer on a car 15 to 17 years old is $560, and only 2.8% of requests on cars 10 years and older got no offer at all.
Does a used car lot offer more than a franchise dealership?
Not as a rule. An independent lot has the same cost stack as a franchise store, reconditioning, holding and overhead, and it can’t give a trade-in tax credit unless you buy from it.
A franchise dealer of your car’s own brand can sometimes offer more if the car qualifies for its certified pre-owned program; the brand dealership guide covers when that happens.
Should I fix my car before selling it?
For a dealer trade-in, cosmetic fixes rarely pay off. Dealers budget their own reconditioning costs regardless of what you’ve already done, so a detail rarely adds what it cost to their offer.
For a private sale, cosmetic fixes usually do pay off. A clean, well-presented car tends to sell faster and attract stronger offers.
Mechanical repairs are different: they rarely add more to the sale price than they cost. Which repairs count has the ones that do.
What’s the fastest way to sell my car?
Junk car buyers like Peddle and Wheelzy pick up within 24 to 48 hours for cars in any condition. Traditional dealers complete trades the same day you visit.
Online buyers like Carvana typically schedule pickup within 3 to 5 days. Private sales are the slowest option, taking weeks to months depending on your car and local demand.
