The quiet worry behind typing your plate into a sell-my-car page is that the offer is bait for a showroom. Across the buyers we track, not one states that you must buy a car to sell one, and two say so outright: Cars.com describes its dealer offer as carrying 'no obligation to buy a replacement vehicle', and Kelley Blue Book calls its Instant Cash Offer free with no obligation. Where the sites differ is whether the number can be spent as trade credit instead of cash, and where you have to be to collect it.
The offers that work as cash or trade credit
| Service | If you take cash | Trade option (as stated on site) | Where the handover happens |
|---|---|---|---|
| Kelley Blue Book Instant Cash Offer | Paid by the participating dealer; KBB does not pick up or pay directly | You choose cash or trade-in; the offer shows exactly what dealers will pay | In person at any participating dealer |
| EchoPark | Check | Trade credit; an extra $500 if you sell within 48 hours of the offer | Bring the car to an EchoPark store; offer good 7 days or 500 miles |
| Driveway | Check or digital payment, on the spot | The same offer is usable as trade credit toward a delivered replacement | A Driveway valet picks the car up from home |
| Carvana (Sell/Trade) | Check or ACH at the appointment | Combined sell/trade flow; trade terms not stated on the page we verified | Free drop-off at a Carvana location, or home pickup for an extra charge in specific locations |
| Cars.com Sell & Trade | Instant cash offer from a local dealer, valid 3 business days | Not stated; no obligation to buy a replacement vehicle | Local dealer |
Kelley Blue Book is the purest version of the choice because it never touches the car: the offer is redeemed at a participating dealer, and at that counter you decide between cash and trade. Driveway is the only entry that pairs a trade path with a valet, so the credit goes toward a delivered replacement and you never visit a store. EchoPark's trade credit sits behind a store visit, where staff confirm the online quote matches the car. Carvana's sell page is labelled sell-or-trade, but the page we verified states only the cash side: check or ACH at the appointment, after an inspection confirms the car matches the appraisal information.
The buyers that only describe cash, and why that can be the point
Every other buyer in our data describes payment and nothing else: AutoNation by check or instant Zelle after an in-store inspection, CarMax on the spot at a store or home pickup, webuyanycar.com by check, ACH, wire or Zelle at the branch, GiveMeTheVin by check the same business day, Wheelzy in cash on the spot, and CashForCars.com, Peddle and WhipFlip at handover. None of those entries mentions a trade path, and that is not a gap. Trade credit is spent with the retailer that issued it, so it is only worth as much as the car you would buy there. A check goes to any dealer's trade desk, which is exactly what Kelley Blue Book's offer is built to show you before you walk in.
If you still owe on the car
Trading in usually comes up because there is a loan on the car, and only three entries address that. AutoNation states it handles the loan payoff deduction as part of its same-day payment. WhipFlip promises immediate lienholder payoff, though it operates only in Pennsylvania, Ohio, Delaware, New Jersey and part of Minnesota, and its full offer requires a smartphone. DamagedCars.com warns from the other direction: it requires keys, a signed title and vehicle access, and lien-held titles add delay. No other sell page we track mentions a loan, so if you owe money, ask before you accept.
What to check before choosing trade over cash
- Whether trade and cash are the same number. Driveway states the same offer works either way; EchoPark's extra $500 applies only if you sell within 48 hours.
- Where you have to be. Kelley Blue Book and EchoPark are redeemed in person; Driveway and Carvana pick up from home, though Carvana's pickup carries an extra charge in specific locations.
- Whether the number survives inspection. EchoPark requires the car to be in the same condition as at the time of the offer; Carvana pays only after its inspection matches the appraisal.
- The clock. EchoPark's offer is good 7 days or 500 miles; Cars.com's lasts 3 business days; Kelley Blue Book's validity is not stated on its sell page.
