Hey Product Hunt. I have bought a few used cars over the years and every single time the seller had a totally reasonable explanation for why they were selling. Every single time I found out the real reason later, usually at a repair shop. The thing is, almost nobody brings a mechanic with them when they go look at a car. And even if you know cars, the seller has been living with that vehicle for years. They know exactly what it does and does not do. You get a 20 minute test drive and their word for it. I got tired of it so I built Idle Check. You paste in the listing or the VIN, and it pulls the live NHTSA recall data for that exact vehicle, flags the most common failure points for that make and model and mileage, estimates what repairs would actually cost you, reads the listing text for red flags, and writes you a negotiation script based on what it found. First three findings are always free. Full report is $4.99, one time, no subscription, no account needed. Would genuinely love to hear from anyone here who has been through the same thing buying a used car. And if you try it, let me know what you think.
