Automotive RepairPart Identification & Selection4HighOwner$ explicit
A California owner of a 2004 Subaru Outback cannot find a CARB-compliant catalytic converter, causing the car to run terribly with surging and jerking at low speeds.
No CARB-compliant catalytic converter is available for this vehicle, and even aftermarket manufacturers like MagnaFlow list the part but cannot supply it.

CARB-Cat Finder
A specialized database and alert service that tracks availability of CARB-compliant catalytic converters for older and rare vehicles.

Key Features
- Vehicle-specific CARB-compliant part search across multiple suppliers
- Back-in-stock alerts and waitlist for out-of-stock parts
- Alternative solution recommendations (e.g., used OEM, custom fabrication with BAR approval)
- Integration with smog check stations to verify compliance
Target Users: Car owners and independent repair shops in California and other CARB-regulated states dealing with hard-to-find emissions parts for older vehicles (10+ years old).
Revenue Model: $9.99/month subscription for premium alerts and priority support; $4.99 per single-part availability report
