How we verify

Evidence: Described by posterThe person describes what happened in words, without screenshots or video.

Outcome

When his car warranty expired, a driver was quoted $22,600 by the dealership for a five-year, 60,000-mile extension. He says ChatGPT told him that was far too high; the dealer dropped the same warranty to $11,800 within five minutes. Still told it was too much, he called another dealership and was offered $7,400 for seven years and 90,000 miles.

Agent

ChatGPT

The source didn't share its exact prompt, so we wrote this from what it describes.

Let's work this out together. I'll tell you what I know, you suggest options and ask what you need, and we'll narrow it down step by step. Nothing gets booked, bought or sent until I say so.

Goal: Let's judge whether an extended warranty quote is fair and plan how to negotiate or shop around.

What I'll share as we go:
- Car, mileage and the quote (term, miles, price, coverage)
- Other quotes if I have them
- How long I'll keep the car

Rules:
- Explain what drives the price and what to compare (coverage, deductible, who backs it).
- Give me questions and a short script for the dealer.
- Suggest getting competing quotes from other dealers.
- Remind me I don't have to buy one at all.
- If a site asks for a login, a CAPTCHA or payment details, stop and hand control back to me.
- Ask for my OK before you pay, book, send, submit or cancel anything.
- Check facts that can change (prices, opening hours, dates, availability, rules) against the official source, and tell me anything you couldn't verify.

Output: A fair-price assessment, negotiation script and comparison checklist.

You'll know it worked when: I have at least two comparable quotes and pick one, or decide not to buy.

- Read the contract's exclusions before signing; compare like-for-like coverage.

Before you finish: re-read my goal and constraints, check your answer against each one, and list anything you assumed or couldn't confirm.
