Best Places to Sell a Used Car: Instant Offers, Trade-In or Private Sale
By CarWhere Research · Updated November 2026
For the most money, sell privately: KBB says trade-in value runs below private-party value. For the fastest sale, collect two or three instant offers the same day (CarMax's lasts seven days, KBB's Instant Cash Offer seven days excluding Sundays) and take the best firm one. Trading in can win where your state taxes only the difference.
Facts below are from each company's own published pages and government sources, checked November 2026. Policies change, so verify the current terms before you act.
Where to sell a used car, compared
Terms below come from each company's own published pages or filings.
| Option | How the offer works | Pickup and payment | Source |
|---|---|---|---|
| CarMax | Online offer “in two minutes or less”; good for seven days | At-home pickup for most customers (fee could apply); express drop-off finalizes in under 30 minutes with payment in hand | CarMax, Nov 2025 |
| Carvana | An “automated, conditional offer” from an online tool | Schedule pickup at home, or drop off at a Carvana location and receive payment | Carvana 10-K |
| KBB Instant Cash Offer | “A real offer for a specific amount”; valid 7 days, not counting Sundays | Redeemed at a participating dealer during business hours, pending inspection | KBB FAQ |
| Peddle | Online offer; seven days to accept, after which it could change | Free pickup; the driver confirms the car and pays by check | Peddle |
| Dealer trade-in | Appraisal against your next purchase; KBB Trade-In Value assumes this | Applied to the new deal; can cut sales tax in states such as Texas and Missouri | KBB FAQ |
| Private sale | You set the price; KBB Private Party Value is the benchmark | You handle title, release of liability and payment | CA DMV |
The two-offer method
Instant offers are firm numbers, which makes them useful even if you end up trading in. Request two or three on the same day, using identical, honest condition answers, so they're comparable and none expires before you decide. Then:
- Take the highest firm offer as your floor.
- Ask your dealer to match or beat it on the trade. KBB says its Trade-In Value assumes you're buying from the same dealer, so the trade is part of the negotiation.
- Compare both against current used-car values for your model, and against what a private buyer would pay.

Trade-in tax credit: when the lower offer wins
In some states, including Texas and Missouri, trading in reduces the sales tax on your next car. The Texas Comptroller charges motor-vehicle sales tax at “6.25 percent of sales price, minus any trade-in allowance” (Texas Comptroller). Missouri law likewise taxes only the part of the price that exceeds the trade-in allowance (RSMo §144.025).
California is different. The CDTFA tells dealers, “You cannot deduct the allowance for the trade-in,” with a worked example where a $20,000 sale with a $4,000 trade-in is taxed on the full $20,000 (CDTFA).
On a $40,000 purchase in Texas, a $15,000 trade-in saves 6.25% × $15,000 = $937.50 in state sales tax. A private buyer would have to pay roughly that much more to beat the trade. Run your numbers in the trade-in vs. private sale calculator.
Selling privately: the paperwork and the scams
- California: sellers “must also submit a Notice of Transfer and Release of Liability (NRL) within 5 days,” and a smog certification may be required (CA DMV).
- Texas: give the buyer a properly signed title with the date of sale and odometer reading, and submit a Vehicle Transfer Notification. “The seller may keep their license plates for future transfer to another vehicle” (TxDMV).
- Payment: the FTC says, “Don't accept a check for more than the selling price,” warns that it can take the bank weeks to spot a fake check, and suggests an escrow or online payment service when selling online (FTC, Feb 2025).
Other states have their own forms and deadlines, so check your DMV's seller page before you hand over the keys.
Where to sell your car: FAQ
What is the best place to sell a used car?
It depends on whether you want the most money or the least hassle. A private sale usually pays most, since KBB says its Trade-In Value is lower than Private Party Value. For speed, get two or three instant offers the same day (CarMax, Carvana, KBB Instant Cash Offer, Peddle) and take the highest firm number.
What are the best instant cash offer websites?
The large national ones include CarMax (online offer in two minutes or less, good for seven days), Kelley Blue Book Instant Cash Offer (valid 7 days not counting Sundays, redeemed at participating dealers pending inspection), Carvana (an automated, conditional online offer with home pickup or drop-off) and Peddle (seven days to accept, free pickup, paid by check).
How long is a CarMax offer good for?
Seven days. CarMax’s November 18, 2025 announcement says customers can “get an online offer in two minutes or less; it’s good for seven days to compare options.” At-home pickup is available for most customers, though availability varies by location and a fee could apply.
Does Carvana pay what it offers?
Carvana’s annual report describes its online offer as “automated, conditional.” The final amount depends on the car matching what you described. Report condition honestly, and get at least one competing offer on the same day so you have a fallback if the number changes. Our Carvana selling review covers the process.
Is trading in better than selling privately?
Sometimes, once sales tax is counted. In states such as Texas and Missouri, tax on your next car is charged only on the price minus your trade-in allowance. California does not allow that deduction. A smaller trade-in offer can still come out ahead in a state with the credit.
How do I sell my car privately and safely?
Sign the title over with the date and odometer reading, then file your state’s release: California requires a Notice of Transfer and Release of Liability within 5 days; Texas asks sellers to submit a Vehicle Transfer Notification. The FTC warns never to accept a check for more than the sale price.
