Is there a reason why you are keeping the site a secret? I had no idea it existed, but a quick Google search for “motability dealers website” lead me to here: So Motability is hardly hiding it from the public.
Unless the policy has changed (@wmcforum ?), as many long term members here will remember, there are/were certain ‘non-customer facing’ websites members hereabouts were not supposed to directly link to. The other Motability website being one of those so affected.
