Check a Used Car Before Buying
Look up MOT history, inspection records, and recall status for a used car before handing over money.
Quick answer: Use the Vehicle Data tool through ToolRouter to check a used car before buying directly from Claude, ChatGPT, Microsoft Copilot, and OpenClaw — connect once, then drive it with plain-language prompts. No code required.
ToolBuying a used car without checking its history is one of the most common and costly mistakes people make. A car can look perfect and have a clocked odometer, hidden accident damage, outstanding recalls, or a string of advisory failures that the seller hasn't disclosed. The information exists in public records — but knowing which checks to run and how to interpret the results is where most buyers fall short.
Vehicle Data combines MOT history, plate lookup, inspection records, and recall checks in one place. You can see every MOT result, the mileage at each test, any advisories flagged, and whether the vehicle has any outstanding safety recalls — all from the registration plate.
Private car buyers, motor traders, and vehicle inspectors use this to verify a car's condition history, catch mileage discrepancies, and ensure outstanding recalls have been addressed before purchase.
How to check a used car before buying with Claude, ChatGPT, Microsoft Copilot, and OpenClaw
Use Claude with Vehicle Data to investigate a used car's history and get an interpreted verdict. Claude can read the MOT history, spot mileage inconsistencies, identify recurring advisory failures that suggest an underlying problem, and flag outstanding recalls — explaining what each finding actually means for the car's condition and your decision.

How to check a used car before buying with Claude
Once connected (see setup above), use the Vehicle Data tool:
- Provide the registration plate of the car you are considering.
- Ask Claude to look up MOT history, plate data, inspection history, and recall status via `vehicle-data`.
- Ask Claude to flag any mileage discrepancies, recurring advisory failures, or outstanding recalls.
- Ask Claude to summarize whether this car looks like a sound purchase or whether the history raises concerns.
Example prompt for Claude
Try this with Claude using the Vehicle Data tool
Use vehicle-data to check the history of this car: registration plate AB12 CDE. Run dvsa_mot, plate_lookup, inspection_history, and check_recalls. Flag any mileage discrepancies, recurring advisory failures, or outstanding recalls. Then give me a clear verdict: does the history suggest this is a sound car to buy or are there red flags I should ask the seller about?
Tips for Claude
- Look for mileage jumps or drops between consecutive MOT tests — these are the clearest sign of clocking.
- Recurring advisories for the same issue across multiple MOTs suggest the problem was never fixed.
- Check recall status even if the car has passed recent MOTs — recalls are manufacturer safety issues, not MOT items.
Use ChatGPT with Vehicle Data to check a used car's history and produce a formatted report you can reference during negotiation or share with someone helping you with the purchase. ChatGPT formats the raw MOT, recall, and inspection data into a clear, scannable report with a buying recommendation.

How to check a used car before buying with ChatGPT
Once connected (see setup above), use the Vehicle Data tool:
- Provide the registration plate and any information the seller has given you.
- Ask ChatGPT to run MOT history, plate lookup, inspection history, and recall checks via `vehicle-data`.
- Have ChatGPT produce a formatted report with sections for MOT history, mileage timeline, advisories, and recall status.
- Ask for a buying recommendation and a list of questions to ask the seller based on any findings.
Example prompt for ChatGPT
Try this with ChatGPT using the Vehicle Data tool
Use vehicle-data to check registration plate AB12 CDE. Run dvsa_mot, plate_lookup, inspection_history, and check_recalls. Produce a vehicle history report with: MOT pass/fail timeline, mileage at each test, notable advisories, recall status, and a buying recommendation. Include a list of questions I should ask the seller.
Tips for ChatGPT
- Ask for questions to put to the seller alongside the report — specific questions are more useful than general warnings.
- The mileage timeline is often the most revealing section — ask ChatGPT to highlight it at the top of the report.
- If there are outstanding recalls, ask ChatGPT to explain what the recall covers and how serious it is.
Use Copilot with Vehicle Data to pull structured vehicle history data for an automotive application, fleet management tool, or dealer management system. Copilot is best when the history data needs to be typed, schema-matched, and integrated into an existing codebase.

How to check a used car before buying with Copilot
Once connected (see setup above), use the Vehicle Data tool:
- Identify the registration plate and define your application schema for vehicle history data.
- Ask Copilot to run `dvsa_mot`, `plate_lookup`, `inspection_history`, and `check_recalls` via `vehicle-data`.
- Have Copilot return the combined result as typed JSON matching your schema.
- Integrate the output into your vehicle listing, fleet record, or inspection system.
Example prompt for Copilot
Try this with Copilot using the Vehicle Data tool
Use vehicle-data to check registration plate AB12 CDE. Run dvsa_mot, plate_lookup, inspection_history, and check_recalls. Return JSON: {registration: string, make: string, model: string, mot_history: Array<{date, result, mileage, advisories}>, outstanding_recalls: number, history_verdict: string}.
Tips for Copilot
- Include `history_verdict` as a computed string (clean/advisory/concern) so your UI can display a clear status badge.
- Return `outstanding_recalls` as a number so your app can flag vehicles with open recalls with a single comparison.
- Keep `mot_history` as a sorted array (newest first) for consistent display.
OpenClaw lets you run vehicle history checks across an entire dealer stock list, auction batch, or fleet inventory in a single job. This is the right approach for motor traders, fleet managers, and auction buyers who need to assess multiple vehicles at once rather than one at a time.

Once connected (see setup above), use the Vehicle Data tool:
- Prepare the list of registration plates to check.
- Run `vehicle-data` with `dvsa_mot`, `plate_lookup`, `inspection_history`, and `check_recalls` for each plate.
- Filter to vehicles with mileage discrepancies, recurring advisories, or outstanding recalls.
- Generate a batch history report ranked by risk level for the purchasing or fleet team.
Example prompt for OpenClaw
Try this with OpenClaw using the Vehicle Data tool
Use vehicle-data to check these registration plates in batch: AB12 CDE, XY34 FGH, LM56 JKL. For each, run dvsa_mot, plate_lookup, and check_recalls. Return results with registration, make, model, mot_pass_rate, outstanding_recalls, and a risk_flag (clean/advisory/concern) in a stable schema.
Tips for OpenClaw
- Use `risk_flag` as a single-field summary so the batch report can be sorted and filtered quickly.
- Prioritize checking vehicles with outstanding recalls — these can affect resale value and liability.
- Run the batch before an auction or dealer visit, not after, so you have decision-ready data on the day.
