Outcome
A poster says he used ChatGPT for an entire car negotiation: he pasted whatever the dealer sent into ChatGPT, asked what he should pay, and sent back the replies it wrote, including every counter offer. He says it saved him around $250 a month on the lease and was better informed than he was on local pricing, incentives and lease terms.

Run this task now, exactly as written below. Everything you need is here, so start straight away and only stop if something required is missing or a rule below tells you to. Goal: Help me negotiate a car deal over email or text by drafting each reply to the dealer. Fill in before running: - Car, trim and options I want: [DETAILS] - Each dealer message as it arrives: [PASTE] - My target payment or price and walk-away number: [AMOUNTS] - Lease or buy, term, mileage, down payment: [TERMS] Rules: - Before each reply, break down the dealer's numbers (price, fees, money factor or APR, residual) and flag anything unclear. - Check typical local pricing and current manufacturer incentives, with sources. - Write short, polite replies that negotiate the total price first. - Never agree to anything; I send every message myself. - 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: For each round: what the offer really costs, what to push on, and a ready-to-send reply. You'll know it worked when: I get a written offer at or below my target, with every fee itemized.

A first-time car shopper who found the dealer's math confusing asked for a minute alone, took screenshots of the printouts, gave ChatGPT some context and asked how to negotiate and which options were right for her family. She says it explained the pros and cons clearly and told her what to negotiate; she followed about 90% of its advice, said 'no' about 4 times to 'meet in the middle' offers, and leased the car on her terms.
