Deal score

A simple 0–10 score with a verdict: Excellent, Good, Fair, Overpriced or Avoid.

Recalls to ask about

Why check a Marketplace car first?

Private sellers on Facebook Marketplace set their own prices, and listings rarely mention the problems a model is known for. Two cars with the same year and miles can be thousands of dollars apart.

Checking the value, the model’s weak spots and open recalls before you reach out tells you whether the car is worth the drive, and gives you real numbers to negotiate with.

FAQ

How do I know if a Facebook Marketplace car is a good deal?

Compare the asking price with the car’s fair private-party value for its year and miles, then check what usually breaks on that model. AutoGauge does both from the listing and gives you a 0–10 deal score.

Do I need a Facebook account?

You need to be able to open the listing. On a computer, open it in Chrome and click Scan. On a phone, share or paste the listing link into AutoGauge.

Does it work for listings outside Facebook Marketplace?

Yes. In the app, take or upload photos of any car, from any website or in person, and add the details. AutoGauge reads the car and returns the same report.

Is AutoGauge free?

AutoGauge is free to download, and the Unlimited plan starts with a 3-day free trial. You can also buy a scan pack instead of subscribing. The Chrome extension gives new users one free scan.

Does it replace a pre-purchase inspection?

No. AutoGauge tells you what the car is worth and what to look at. Still inspect the car in person or with a mechanic before you buy.
