Most pre facelift 3.0/3.0i SE cars came with M Sport suspension from the factory, although you could opt for Se suspension if you wanted I've never seen one that did. In fact the only pre facelift 3.0I/SE I know of running SE suspension is mine and that's only because I fitted it.
Post face lift wise 3.0 SE doesn't m sport and the sport does.
You can use one of the online vin checkers to see what yours came with from the factory, it will list which suspension option is fitted.
If you google "suplex catalogue" you should find a link to their pdf which list all the various options. There is a number of choices for the E85/6 varying with engine size, transmission and even options etc
