You can't remove the number of owners from your advert. It must be shown on all adverts for transparency to potential buyers.
But if the number of owners is wrong, you can edit the advert to show the correct number. To do this:
- Head to 'Account' and 'Vehicles you're selling'
- Select 'Manage adverts'
- Then 'Edit advert'
- Under 'Overview', select 'Edit owners, service history, MOT and seats'
- Select the right number of owners, then select 'Looks good, continue'
- Make sure you select 'Publish changes' to save the updated info
