Hey Mulga
Hope you don't have to wait too much longer to get your hands on the GQV!!
All the accessories are being fitted by the dealer and, for the most part, are apparently "in stock". When I originally enquired, my dealer just asked for the product codes and said that anything on the website was definitely available. When I asked about the illuminated tread plates, they confirmed with 'Parts' that they're also available. They are going to order all the parts in advance, so they can be painted, etc and ready to fit as soon as my car arrives
When I went in to find out pricing, they did have an accessories list they let me take a look at, which had pricing on it, but didn't provide me a copy unfortunately

I do have individual pricing for each of the parts I'm getting though...
Let me know if there's any more info I can give you which might help?
