What the prompt labels mean

The person didn't share their exact words, so we wrote this from what they described. We haven't tested it, and they didn't use this exact version.

I want to buy this new car from a dealership far from home. Here's the VIN and listing. Research how long it's likely been on the lot and what the market looks like, then help me negotiate by text: I'll paste each message from the salesman, and you suggest my reply. Keep the price separate from rebates and incentives.

Before you start, ask me 1–3 short questions about the details below and wait for my answers. Once I've answered, confirm the plan in one line and run the whole task start to finish.

Goal: Coach me through negotiating a car purchase by text or email, with the out-the-door price in writing.

Questions to ask me first:
- Which vehicle (year, make, model, trim) and dealer?
- What rebates or financing offers do you qualify for, and do you have outside loan approval?
- What's your walk-away out-the-door price?

Inputs (fill in or confirm):
- Listing and VIN: [LISTING / VIN]
- Comparable listings I found: [COMPARABLES]
- Incentives I qualify for: [INCENTIVES]
- Pre-approved loan offer: [LENDER / APR / TERM]
- Walk-away price: [MAX OUT-THE-DOOR]

Rules:
- Negotiate the selling price first, then apply rebates separately.
- Always ask for an itemized out-the-door price including fees and add-ons.
- Flag dealer add-ons (paint protection, etching, warranties) and draft a request to remove them.
- Show your source for any lot-time or market-price claim, and label guesses as guesses.

Checkpoint: Before I reply to each message, show me your suggested reply and why.

If you get stuck: If the dealer won't itemize or adds products, draft a polite walk-away message.

Verify before you finish: Compare the final offer with my walk-away price and outside loan, including total interest paid.

Output: Suggested replies, a running offer table and a final itemized comparison.

Done when: I have an itemized out-the-door price in writing that's at or below my walk-away number.

Outcome

A Reddit user posting as The_Maroon said ChatGPT guided almost every step of buying a new car from a dealership about 10 hours away. It researched the vehicle's VIN, how long it had sat on the lot and market conditions, then suggested contacting a salesman, establishing interest and moving the talks to text. The buyer pasted the salesman's messages into ChatGPT and used its replies, keeping the selling price separate from rebates and incentives, and used it again in the finance and insurance office. After several days of texting, the buyer signed electronically and reports about $6,300 off sticker and 4.84% financing over 66 months with $20,000 down. Commenters pointed out that the vehicle was never named, and dealer-applied paint protection and window etching added roughly $1,300, so the real savings can't be confirmed.

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

Known limitations

PartialThe source says it only partly worked, or had a significant problem a person had to deal with.

What went wrong: The deal closed, but the vehicle was never named and about $1,300 in add-ons were included, so the claimed savings are unverified.
