Partial The Chrome side panel, NHTSA and Transport Canada recall and crash lookups, and fuel-cost data are all public and vibe-codeable. The 0-100 deal score needs market price comparables, which is a proprietary dataset.
What it would actually take: Build a Chrome extension (Manifest V3) that parses listing pages and calls the NHTSA vPIC, recalls, and SaferCar APIs, plus Transport Canada's recall data and EPA fuel-economy data. The deal score requires a large, continuously updated corpus of comparable vehicle listings and prices, which must be scraped, licensed, or otherwise acquired. That data pipeline is the hard part.
