advertising in sub forums

[Szek]

I'm considering VBulletin for a forum but i have some questions:

Can I have a 'free' board with 'paid' sub forums? - so the public have access to the general site but must be registered/paid subscribers to access certain sub-sections

within those sub-forums can I specify advertising? - I want certain advertising to appear only to registered/ paid members of that particular sub-forum.

As an example: let say it's a forum on cars - it's a public forum but if you want to see items for sale you have to be registered. Once you are registered you can see more of the forum but not the toyota sub-forum - if you register for that forum you can access it and see advertising only for members of that sub-forum. The critical thing is the advertising - I need to restrict certain advertising to certain groups.

is that possible?

Paid subscriptions can do the first bit easily with the subscription manager and user groups.

You can do the second bit with conditionals and/or custom mods.
