Ask follow-up questions, get possible causes ranked by likelihood, and understand what to do next. REAL MARKET VALUE BEYOND KBB Track your vehicle's market value using real-time data from live auctions and private sales — not just book estimates.

Every guide includes a list of tools and parts you'll need, difficulty ratings, and cost estimates. Ask the AI questions as you work.

Perfect for households with multiple vehicles or fleet management. MILEAGE LOGGING Keep a complete record of every service, every mile, and every dollar spent. Your vehicle's full ownership history, always up to date and easy to share when it's time to sell. ROUTE CREATION Create accurate, specific routes using waypoints, pitstops, and multiple destinations so you can drive the roads you want to, not the ones the mainstream map apps suggest. Share routes with others and see them on your map while you drive. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
