Once logged in your first option on the top left of the screen is:
Manage Vehicles
Select the vehicle you wish to update or add a vehicle using the orange button.
As we partner with the DVLA your vehicles details should populate automatically, get in touch with us if these details are incorrect.
The sections can be edited simply by clicking on them which flips the sections allowing you to add dates, amend information and most importantly add emails to send reminder notifications.
