Buying a used car privately is where the scams are: a price that is too good to be true, a seller who wants a deposit before you have seen the car, a shipping or "I moved" story so you can never meet, a fake eBay or escrow "protection" link. CarBluff checks all of it before you ever message the seller. Paste the listing link or upload a screenshot, and it runs 20+ checks on the link, the price against the local market, and the seller's own wording, then returns a 0 to 100 trust score with every red flag explained in plain language. It works on Facebook Marketplace, Craigslist, OfferUp, and AutoTrader. First scan is free with no account. Built for regular buyers, not dealers.

    Why? Because I built certdecoder.com and couldn’t find a decent place to submit it. So I said screw it — I’ll build my own. With blackjack and hookers. - Source: dev.to / over 1 year ago
