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.
01Why bot
- Email negotiation is mostly clear writing and comparison.
- Focusing on out-the-door price avoids common dealer tricks.
- It flags add-ons you can decline.

How each run works: we fill the prompt with a made-up sample, run it once in Llama 3.3 70B, and GPT-OSS 120B grades the answer against the prompt's own rules. Word limits are counted by code, and every quote flagged as made up is checked against the full answer. Your results can differ. How we test.
