Used car sellers - especially dealers or marketplaces - often lose track of vehicles after they’re sold. Some buyers flip them quickly, while others report issues later. This tool allows sellers to register license plates of sold cars and receive alerts when the same plate appears online again - on resale sites, auction boards, or public forums. This is useful for tracking reputation issues, flipping fraud, and even recapturing leads (by offering trade-in upgrades when the car reappears). The system scrapes dozens of classified platforms, matches new listings by plate number (or VIN when available), and sends real-time notifications to subscribed sellers. Build once, then offer this as a passive subscription tool to dealerships, B2C marketplaces, and even private collectors. You get recurring revenue while the tracking engine runs in the background.
Step-by-Step Guide to Success

Allow sellers to upload a CSV or manually register their sold plates (1–1000+).
Match scraped listings to the plate database and trigger alerts by email or Telegram.
Create a user dashboard showing history of matched vehicles and links to new listings.
Add tagging (e.g. sold to John / auctioned) for better internal management.
Offer CSV exports for compliance or CRM import.
Monetize with monthly subscriptions, tiered by number of plates tracked.
Launch partnerships with local dealers, online marketplaces, and used car auction networks.
