Difference between the Avant S line rear bumper and Se/standard one?

[fozworth]

I've not had a good day . Just a few days ago got my s line avant back from the body shop after having the rear bumper re painted only to find today some tosser has stoved the corner of it right in and driven off without leaving any note etc. Total waist of money that was. So I need a replacment . I've seen a couple on eBay at ok money but some don't say S line just Avant . Is there a difference appart from the lower valance which I'm not going to use as I have my sport version to reuse.
