Engineered for Accuracy. Built for Trust.

I'm a systems engineer at a top defense contractor. I built UsedTruth after a "clean" vehicle history report missed a repeated A/C failure pattern, which led to about $1,000 in repairs just six months into ownership.

I wanted a tool that doesn't just summarize PDFs. UsedTruth queries official government databases (NHTSA), recognizes undisclosed collision and maintenance patterns, and gives you negotiation-grade price intelligence when you provide an asking price.

Generic chatbots hedge. UsedTruth takes a stance, because buying the wrong car isn't an academic exercise.

Is It Safe to Drive? Check Active Recalls Instantly.

Don't ignore warning lights or open campaigns. Enter your VIN and we hit the official NHTSA pipeline (decode and recalls) so you see what applies to your vehicle. Free. Bookmark it for every car in your driveway.

Why Choose UsedTruth

Three live products—buying intelligence, DIY planning, and quote defense—built for decision-grade clarity.

TruthAudit · Safety first
Cross-checks recalls and history signals so you aren't comforted by a "clean" PDF while NHTSA or repair patterns tell a different story.
TruthGuide · Symptom to plan
Turns noise, vibration, and leaks into ranked tutorials, parts tiers, and tool notes—so you are not stuck in ten browser tabs guessing trim and engine codes.
QuoteGuard · Line-item defense
Upload the shop quote; we benchmark labor and parts so padded hours and mystery markups surface as questions—not surprises on the invoice.
TruthAudit · Price leverage
When you add an asking price, TruthAudit ties market anchors to the verdict so negotiation isn't a vibe—it's a number.
TruthGuide · Grounded parts
Parts suggestions lean on live search when available—Premium, Standard, and Budget lanes with retailer links you can verify before you buy.
QuoteGuard · Local context
Add ZIP or location to tighten benchmarks—labor allowances and parts bands shift by market, and we surface that in the narrative you take to the desk.

Pro tip: Use UsedTruth before you buy, not after. Prevention is cheaper than repair.

Important: UsedTruth does not replace professional mechanical inspection. We strongly recommend getting your vehicle inspected by a qualified mechanic before purchase. View full disclaimer →
