Once your advert's live, it's not possible to change your package.
Each advertising package has different features to promote your advert to potential buyers. Your advert uses these premium features immediately once it’s live.
If you’re a private seller who buys the Premium package or a trade seller who buys the Ultimate package, you can boost your advert to push it higher up in relevant search results.
You’ll get the option to boost your advert when you create it. You can also boost your advert at any time by going to the 'Vehicles you're selling' area of your account.
