I had one two cars ago. Probably the best all round car I have ever owned.
Facelifted cars as well as the new nose get more kit; different bootlid and LED tail lights, windows that close by remote, rain sensing wipers and auto headlights. Electric seats and rear parking sensors are stock, ignore any dealer that says otherwise. Sport gives you the suspension/bodykit/sports seats/ 18"s / black shadowline trim / multi function steering wheel and more. Much better car than the SE IMO.
Desirable options are leather (very rare without it), Xenons, Bluetooth, Sat Nav, Harmon Kardon Stereo (not great but if its there, why not) and 6CD...other stuff like Sunroofs and 'Futura' leather (upgraded from Dakota) are rare but worth having.
Clubsports are nice but not worth a premium. Estoril Blue, Velvet Purple, Silver or Black, and all it really includes is fancy kick plates, cube alu dash trim, front corner splitters and an ugly spoiler. I wouldn't bother. If you want Auto, tons to choose from. DON'T BUY SSG UNDER ANY CIRCUMSTANCES. It's tosh, and completely different to SMG in the M3.
