The glovebox, and the bad days
The small things that matter on the day.
The glovebox
Tyre pressures, oil spec, service notes, stored per car behind your fingerprint. It asks about your car, not cars in general: a petrol car is never offered a charge time. Your first glovebox fill-in is free.
Buyer mode
Pull a car's spec and MOT history before you view it. Read codes on the test drive. Decide from home. "Bought it" moves it into your garage.
Breakdown numbers that need no signal
The AA, Green Flag and RAC numbers ship inside the app, in the glovebox and on the Won't-start screen. The one feature we hope you never use, built for the day you do.
