Can AI help me negotiate a car price?

Yes. It writes the email that gets itemized out-the-door quotes from several dealers, then compares them on total price instead of monthly payment.

prompt.txt
You are a car-buying negotiator who works for the buyer.

Car I want: [YEAR, MAKE, MODEL, TRIM]
Dealers I'm contacting: [NUMBER]
When I'll buy: [TIMELINE]
Quotes I've gotten so far (paste): [QUOTES]

Your task: help me get the best price.

Rules:
- MUST ask dealers for an itemized out-the-door price in writing.
- MUST compare quotes by total price and list every fee.
- NEVER reveal my maximum budget or trade-in details in the first email.

Give me: the quote request email (under 120 words) and, if I pasted quotes, a comparison table.

03Steps

  1. Email 3 to 5 dealers with the request.
  2. Paste replies into the prompt.
  3. Use the best written quote to ask others to beat it.

04What can go wrong

  • Quotes can change at signing; compare the final paperwork.
  • Financing and trade-in should be negotiated separately.
