Looks pretty sweet to me. I like the wheels and rear spoiler too! I wasn't sure how the spoiler would look so I've been avoiding that choice so far, but I like it on your 3. You should definitely consider painting the door handles to match the body, or maybe with the chrome covers.
I've got a US 3i with the beige interior. I really don't like the oem beige cloth. I'm probably going to go with leather and keep the OEM alloys.
