Last updated , from the Aug 2026 data month. Every price is the advertised asking price when the car left the dealer's website, never what it sold for.

What should I ask for my car if I sell it myself?

Start from what dealers listed cars like yours at. In Aug 2026, used 2019 Toyota Camry SEs in Florida listed at an $18,008 median ($15,571 to $20,010) after 26.1 days, and with 50,000 to 70,000 miles the national median was $21,590. Ask for your exact car in your state, then at your mileage.

  1. Prompt

More questions

What is Sold Market Data?

Monthly statistics on cars that left tens of thousands of US franchise and independent dealer websites since January 2021: units sold, the priced sample, the median and mean asking price, the odometer and days on market, grouped by model, trim, year, seller or group. Every price is the advertised asking price when the car left the website. A private buyer compares your price with these dealer asking prices, so they are the market to price against.

Does it include private-party sales?

No. It counts cars that left US dealer websites, so it shows what a buyer sees at dealers for cars like yours. Dealer prices can include reconditioning and sometimes a warranty, so set your own price with that in mind.

How current is the data?

It is monthly, and each month lands one to two months after it ends, so price against the latest month, then check live listings near you. The examples on this page are from Aug 2026. It covers US dealers only, back to January 2021, at most 12 months per call.

How many sales back each figure?

Every row states its units sold and its priced sample, the sales with an asking price behind every price figure. A row on fewer than 30 priced sales is marked as a thin sample: read it as a direction only. Drop the trim or widen to nearby states until the row clears 30.

What does a call cost?

$3.00 per call unit, paid from your prepaid balance and only after a successful call; a refused or failed call costs nothing. Every prompt on this page is 1 unit ($3.00), so all 8 prompts come to 8 units ($24.00).

How do I get started?

Add the MarketCheck AI Desk connector to Claude or ChatGPT; it is free to add, and ChatGPT works on Free accounts too. Then paste a prompt from this page or ask in your own words, and each call is charged to your prepaid balance only when it succeeds.
