I'd go for:
Xenons + plus headlight wash (can't have xenons without it)
Hex trim with EB. I ordered hex with black trim but my car was delivered with EB. I really like it now and I'm so glad it came with it. It just adds that little bit of colour to the interior..
Get the windows tinted after market. AW needs tinted windows.
Other than that your budget will be blown. Standard Audio is great for me. If I'd gone from HK to it then I might be a little disappointed but its OK in my book.
The non xenon F30s look a bit boring in my opinion. Plus they are miles better for driving at night, it's not just about the cosmetics..
