Build an AI car maintenance tracker for car owners and family fleets with these features:
1. Garage: add vehicles by VIN lookup or manual entry (make, model, year, current mileage).
2. Service schedule: automatic maintenance schedule from the vehicle database (oil, tires, brakes, filters, battery), with mileage and time based reminders.
3. Odometer logging: quick mileage entry with rolling average miles per week to predict upcoming services.
4. Service log: record work done with cost, shop, receipts, and photos, building a maintenance history that increases resale value.
5. AI symptom triage: describe a sound, smell, or warning light in plain English and get likely causes ranked by urgency, cost range estimates, and questions to ask the mechanic.
6. Cost tracking: spend per vehicle per year by category, with alerts when a car is costing more per month than its value suggests.
7. Pre-trip checklists and a winter prep checklist, auto-generated per vehicle.
8. Resale package: one click to export a full verified maintenance history PDF for buyers or dealers.
