As of 13 August 2026, AI can make a claim against a used car dealer.

What to actually do

1. Hand it to a person

   The route this page recommends

   A person who owns the outcome does this end to end, worth it when the failure is dear.

2. Use a tool built for this

   Second choice

3. Do it yourself

   The distant third

   A chat interface, chat-fluent skill, and roughly 30 minutes until you can act on the result.

   How to actually do it

   1. Open a folder for the dispute and gather the sales advert, invoice, finance or warranty documents, messages, call notes, photographs, inspection reports, repair invoices and recovery records.
   2. Write a dated timeline from the purchase to the present, separating what the dealer said, what happened to the vehicle, when you reported each problem and how the dealer responded.
   3. Open the relevant GOV.UK guidance for consumer disputes and the official court or alternative-dispute process that may apply, then note the current process and any deadlines without relying on an AI summary alone.
   4. Paste the timeline and evidence into a chatbot using the prompt, removing unnecessary personal and financial information and asking it to identify missing documents before drafting.
   5. Compare every sentence in the proposed letter with the original advert, contract, messages, reports and receipts, then delete or correct anything the documents do not support.
   6. Choose the remedy you can justify, ask the dealer for a written response, send the checked letter with copies rather than originals, and keep proof of delivery and the complete evidence folder.
   7. If the dealer rejects the complaint, the amount is substantial, court proceedings are likely or the legal position is unclear, take the evidence and draft to a solicitor or the relevant official advice or dispute service before escalating.

   Prompt

   Help me prepare a factual complaint and possible claim against a used-car dealer in England or Wales. This is not professional advice. Do not decide that I have won, invent legal rights, deadlines, evidence or figures, and do not present uncertain points as facts. First extract a dated timeline, the dealer's promises, the vehicle's reported problems, my attempts to resolve them and the losses I can evidence. Separate facts supported by documents from my recollection and from points that need checking. Then identify missing information and documents. Use only the current official sources I provide or sources you can link to, preferably GOV.UK. Explain in plain English which points I should verify before sending anything, and flag where a solicitor, Citizens Advice or the relevant official dispute process should take over. Draft a concise letter to the dealer that sets out the purchase, defects, evidence, previous contact, requested remedy and a reasonable request for a written response. Do not threaten court action unless I explicitly ask for that wording. Include a document list and a short checklist of every factual statement I must check against the originals. My details and evidence are below:
   
   Dealer name and address: [insert]
   Purchase date and price: [insert]
   Vehicle make, model, registration and mileage at purchase: [insert]
   How and where I bought it: [insert]
   Advert, description and promises: [paste or attach]
   Problems and when they appeared: [insert]
   Inspection, repair and recovery records: [paste or attach]
   Messages, emails and call notes: [paste or attach]
   What I have already requested: [insert]
   Remedy I want: [insert]
   Losses with receipts: [insert]
   Relevant finance or warranty documents: [paste or attach]
   Location in the UK: [England, Wales, Scotland or Northern Ireland]
   
   End with a separate section titled "What to check before sending" and another titled "When to get legal help".
