What a deal checker looks at that you might miss
Most listings are written to generate interest, not to help you evaluate risk. The price looks reasonable at a glance, the mileage sounds fine, and the seller says the car runs great — but none of that tells you whether the price is actually fair for the year, mileage, and condition, or whether the listing is quietly avoiding a question you would ask if you thought to ask it.
A proper car deal ratingchecks the asking price against real market data for that model year and mileage band, not a rule of thumb. It reads the listing text for language that correlates with hidden problems — vague title status, "runs good" instead of a maintenance history, cash-only urgency, or missing VIN and photos. It weighs how much information is present versus missing, because a thin listing is itself a signal.
DealScan combines all of that into a single 0–100 score with a plain-language breakdown of why the score landed where it did, plus a fair offer range so you know what to counter with. Paste a link, the ad text, a screenshot, or a VIN — whichever you have on hand — and the analyzer works from any of them.
A deal checker is not a replacement for a pre-purchase inspection or a vehicle history report, but it is the fastest way to decide whether a listing is worth the drive. Run every listing you are considering through it before you contact the seller, so you walk into the conversation already knowing where the leverage is.
Once you have a score, dig deeper with our price checker for a standalone fair-value estimate, run the VIN lookup to decode the vehicle's history, add fees with the out-the-door calculator, and check long-term value with the depreciation calculator.
Deal checker FAQ
- How does the used car deal checker work?
- Paste a listing link, the ad text, a photo, or a VIN into the analyzer. DealScan reads the price, mileage, year, title status, and seller language, compares the price against market value for that year and mileage, and flags risky wording. The result is a 0-100 deal score with the reasons behind it.
- What does the deal rating actually measure?
- The rating blends price fairness against market data, mileage relative to age, title and history risk, and how much information the listing is missing. A high score means the price looks fair and the listing raises no red flags. A low score means either the price is too high, the listing is hiding something, or both.
- Is the deal checker free to use?
- Yes. Checking a listing takes seconds and does not require an account, email, or payment. There is no limit on how many listings you can check.
- Can it check a listing from any site?
- Yes. It works with listings from Craigslist, Facebook Marketplace, Cars.com, AutoTrader, CarGurus, dealer sites, or a private seller's text message — paste the link or the text and the analyzer handles the rest.
- Does a low deal score mean I should not buy the car?
- Not necessarily. A low score means the listing has risk factors worth investigating further, such as an above-market price or vague title language. Use the score as a starting point for questions to the seller and a pre-purchase inspection, not as a final verdict.
