Vet a used car listing before you buy: history, Buyers Guide and inspection
Have AI help you check a used car's history report, the dealer's Buyers Guide and the listing for red flags before you pay.
1. Copy this prompt
Paste it into ChatGPT, Claude, Gemini or Grok (the free versions work), then replace the [highlighted brackets] with your details. Leave out account numbers and SSNs.
I'm considering a used [YEAR MAKE MODEL] with [MILES] miles for $[PRICE] from [dealer / private seller]. Listing: [PASTE]. History report summary: [PASTE]. Buyers Guide says: [as is / warranty details]. 1) Flag inconsistencies or red flags (title brands, odometer, flood regions, ownership gaps). 2) Build a checklist for an independent inspection, specific to this model's known issues (and tell me to verify those). 3) Tell me what to negotiate and what to get in writing.

What happened when people tried it

Why this works
The problem: Used cars can hide flood damage, title problems or mechanical issues, and buyers rush decisions at the lot.
How AI helps: AI can read the listing, history report and Buyers Guide, flag inconsistencies, and build a pre-purchase inspection checklist.
