TrustThisCar turns car diagnostics into a used-car buying decision
The proposed Android app reads a car’s onboard computer and produces a plain-language report to help buyers decide whether to buy, negotiate, or walk away.
- For
- People considering a used-car purchase
- Worth noticing
- The proposed scan checks readiness monitors and distance counters as well as fault codes, but cannot assess visible wear or accident repairs.
Field notes
The described workflow starts with an ELM327 Bluetooth adapter in the OBD port and takes about three minutes with the ignition on. Beyond fault codes, the scan is said to read freeze-frame records, emissions readiness, live sensor values, and distance counters stored in the engine computer. The page says the report includes a country-specific repair-cost range and a shareable link, while explicitly warning that a scan cannot judge rust, accident repairs, brakes, or clutch condition.
