Prompts for an AI VIN check

Copy a prompt into your assistant once the free OdoTrace connector is added (your assistant must support custom remote MCP connectors; some plans and workspaces restrict them). Replace the parts in square brackets. The mileage check always needs the VIN; a Dutch plate is an optional extra. Look up only a car you are entitled to check, such as one you are buying.

Add OdoTrace to your assistant or run the check in your browser

To try the connector before you have a car in mind, ask it to “Decode VIN 1HGCM82633A004352”, a widely published sample VIN.

Full pre-check

I'm thinking of buying this car. VIN: [VIN]. Advertised mileage: [number] km. Use OdoTrace to decode the VIN, check the official mileage records, find model recalls and compare the mileage with typical figures for cars first used in the same year. For each fact, name the source. Then list what OdoTrace could not check and the five questions I should ask the seller before paying.

Single questions

Does the VIN match the advert?Decode VIN [VIN] and tell me whether it matches an advert for a [year] [make] [model] [body type].

Mileage recordsCheck the official mileage records for VIN [VIN]. Quote the verdict and its reason, and give each source's status, so I can see which found nothing and which were not checked.

Dutch carThis car is registered in the Netherlands with plate [plate] and VIN [VIN]. What does the RDW say about its odometer, and is that confirmed to be the same car as the VIN?

RecallsWhich recalls were published for a [model year] [make] [model]? Keep each register separate and tell me how to confirm whether this car was repaired.

Is the mileage normal?Is [number] km a lot for a [make] [model] first registered in [year]? Give the median, the range, the sample size and the observation period (or where the methodology gives it), and say where the figures come from.

Coverage firstCan OdoTrace check a car imported from [country]? If not, what should I do instead?

What it could not checkBased on these results, what could OdoTrace not check for this car, and what should I ask the seller or have inspected?

A good answer names a source for each fact, quotes the mileage verdict with its reason and gives each source's status. No readings is a gap, not a clean history. Recalls are listed per model, not per car, and use the model year, which registration papers may not show. Typical mileage compares cars by year of first use and is a historical sample, not today's expected reading.
