Know before you buy, not after.
An 8-step guided inspection that turns your phone and an OBD-II adapter into a real pre-purchase check - idle diagnostics, a vehicle-specific visual checklist, an optional test drive, and an AI verdict: Buy, Negotiate, Caution, or Walk Away.
How it works
Plug in your adapter
Connect a Bluetooth OBD-II adapter to the car you are thinking of buying.
Follow the guided inspection
Idle diagnostics, a checklist made for that type of vehicle and an optional test drive.
Get the verdict
Buy, Negotiate, Caution or Walk Away, with a PDF report you can share.
Idle diagnostics baseline
Full fault-code scan (active, pending & permanent), emission readiness monitors, and an idle baseline of coolant temp, RPM, fuel trims and battery voltage - captured in the first few minutes.
Vehicle-specific checklist
A tailored visual & mechanical checklist - panel gaps and frame rust for a car, tow-hitch and 4WD engagement for a truck, chain and fork seals for a motorcycle - not one generic list for every vehicle type.
Optional test drive analysis
Drive it and DriveHub logs the ride; skip the drive and the AI is told plainly it's evaluating a stationary vehicle only - it will never claim to have observed driving behaviour it didn't see.
Odometer authenticity check
Compares the ECU's own internal odometer (where supported) against the seller's stated mileage, and flags a real, deterministic red flag on any mismatch over 500 km - not an AI guess.
AI Buy / Negotiate / Walk Away verdict
Every finding is weighted by vehicle type - a rusted frame matters more on a truck, a worn chain matters more on a motorcycle - and rolled into one clear verdict with a plain-English summary.
Shareable PDF report
A branded, watermarked report covering the verdict, findings, fault codes and checklist - ready to send to a mechanic, a seller, or keep for your own records.
Vehicle Electronics Report
A sibling AI report that reads every current fault code and live reading together, organised by subsystem - ABS/Traction Control, transmission, body electronics and more, tailored per vehicle type - instead of decoding one code at a time.
Inspection history
Every past inspection is saved and browsable later - the verdict, the findings, and the PDF are never a one-shot view.
