If you are a joint buyer and seller at G3, you will have a unique account which allows you to see the website from both perspectives. On the home page, you will see a graph showing how many vehicles you have sold, as well as your account manager and other seller information.
On the right-hand side of the graph is a small arrow.
Alternatively, if you are on your 'My G3' page. to switch between views simply swipe across to view both of your accounts using your mouse (or finger on mobile) and clicking on the graph and swiping left or right to change the views.
