Would suggest Extended bluetooth (for example spotify streaming) think it's 6NK option.
Very happy I chose it, use it every day!
I recon Xenon lights are standard?
What about extended lighting? It's a must have!
I also think I would have chosen the HK audio system, I'm only mildly impressed by the HiFi system, it works but doesn't give you the extra "ompf". Depends on whether you are a music fan or not though..
