Get the 09 Sedan. I was in your same position and I'm so glad I got the sedan. The facelift makes such a huge difference. The coupe didn't get the facelift until 2010.
Logic 7 is amazing if you can find it. Like AlanAZ, my previous BMW also only had the base. The upgraded sound system is pretty good.
Xenons were a requirement when buying my car. I found one with them. It makes such a huge difference.
