JDM Market Pricing

JDM Market Pricing is a private market intelligence dashboard for Japanese domestic market and kei vehicles in the US. It collects dealer and auction listings, normalizes them into a local SQLite database, and turns scattered inventory into searchable comps, valuation context, and import-cost analysis.

What It Does

The app is built for market research that spreadsheets handle poorly: active listings, sold examples, mileage differences, title status, dealer location, make/model aliases, and the little inconsistencies that show up when JDM inventory is scraped from real sites. It keeps raw provenance, then maps vehicles into a canonical schema so similar cars can be compared without hand-cleaning every row.

The dashboard supports listing search, comparable vehicle lookup, fair-market-value estimates, price activity, and landed-cost scenarios. The practical goal is to make import and buying decisions less vibes-based by keeping the source data inspectable.

Pipeline

Local ingestionRun source adapters for dealer and auction listings, parse vehicle fields, and capture source diagnostics.

NormalizationResolve aliases for make, model, trim, and chassis code; standardize mileage, pricing, drivetrain, title, and seller fields.

Private dashboardServe searchable listings, model activity, comps, valuation signals, and import pricing tools from the synced database.

Status

The project is live as a private dashboard and runs on a local-first data flow: scraping and ingestion happen locally, then the SQLite database and cached media are synced to production for serving. The repository stays private because the adapter code includes real source integrations.
