AI-powered used-car risk reports
Don't buy a used car blind — or deaf.
Record the engine and our AI listens for signs of trouble — trained on real automotive fault audio, not guesswork. Add the price, mileage, and any warning codes and we'll tell you whether to buy, negotiate, or walk away.

AI Vehicle Sound Analysis
Hear more than engine noise.
Record a clip of an unusual vehicle sound. A vehicle-noise model checks for patterns such as braking, belt, battery, ignition, and oil-related sounds, while a general audio model tags other sounds it recognizes. Those broader tags are context, not fault diagnoses.
- Vehicle-noise findings are paired with broader sound-event tags
- Every result is evidence-based — confidence, alternatives, and limitations, never a bare guess
- Runs entirely server-side in about a second — no separate app
Other possibilities: low oil noise, ignition noise
- Trained automotive classifier (version 20260925020010) assigned this class 88% probability.
Have a mechanic confirm this finding in person - no audio-only system can replace a physical inspection.
- Audio alone cannot confirm the mechanical root cause - a physical inspection is required.
- This classifier's training data has no verified per-vehicle identifiers, so it was evaluated with a contiguous-block split rather than a true held-out-vehicle split. Treat its reported accuracy as an optimistic upper bound, not a guarantee on genuinely unseen vehicles.

Buy Confidence Score
This 2015 Jeep Wrangler has some issues or open questions worth resolving — use them to negotiate the price or ask the seller for more information. 1 trouble code was reported and estimated repairs could range up to about $800. The asking price ($13,800) is $821 (6%) above our calculated estimate ($11,681–$14,277) — there may be room to negotiate. This is a calculated estimate from typical depreciation for the make, year, and mileage entered — it is not a live comparison to other similar vehicles currently for sale, so treat it as a rough reference point rather than an exact market value.
Mechanical risk
Moderate riskSome mechanical concerns worth investigating before you buy.
- Check-engine light is currently on
- 1 trouble code reported
Price / value risk
Moderate riskThe asking price ($13,800) is $821 (6%) above our calculated estimate ($11,681–$14,277) — there may be room to negotiate.

Maintenance risk
Moderate riskA few maintenance factors are worth asking the seller about.
- Accident history unknown
Inspection risk
High riskImportant information gaps remain — a professional inspection is strongly recommended before buying.
- No VIN provided yet — a VIN history check hasn't been done
- Accident history is unverified
- Private-party sale — less paperwork/warranty backing than a dealer
