As you may already know, Onyx will only allow you to save a vehicle record after you have entered the vehicle details.  This is clearly a problem if you are ordering a pre-registered vehicle as you will not know the registration at the time of the order.

To overcome this we recommend that you enter a unique identifier in place of the registration such as :

By doing this you will be able to create the record which in turn allows you to create the order form and to record the deposit and any payments.

Once the vehicle is registered, you can simply enter the correct registration by pressing the 'Edit' button (the registration is read only within the car sales record).
