Abstract: A mileage recording and service reminding accessory for a shared-use vehicle is provided as a self-contained unit which may be installed as original equipment at the time of manufacture or added as a modification accessory to an existing vehicle. The console includes auxiliary individual odometers or hour meters for different persons authorized to use the vehicle, a master meter within the console, an electric circuit operable to selectively connect a desired auxiliary odometer or hour meter to the master meter, and a service warning meter for registering and displaying pre-selected target mileages for prescribed service. The console also includes a key actuated switch for each of said individual odometers or hour meters. Actuation of each switch activates the ignition and contemporaneously activates only its respective odometer or hour meter to record the vehicle usage for the then current user independently of the usage recorded for the other users.
