If you are bad at / hate having to write down what service items are due on your car then this could be of use to you.
Just enter the car reg, whats due and when (in terms of mileage, time or both). Then save the record. Enter the current mileage of the car you have selected and it'll show you whats due... pretty self explanatory.
Hope someone finds this useful!
