Reply to my complaint:
When implementing new designs, Audi AG look to see what options have been most popular among customers for the UK market and then remove the less popular items. There was a lack of demand for the options you have listed in the UK market therefore they were removed as an option. I am sorry for any disappointment this may cause.
I suggest everyone here emails Audi and complains. I mean the interior design pack! Come on.
I've been following this because I'm hoping to get one ordered but am disappointed with the options as well...
I regards to that response, if someone had more time than I do (or is more OCD than me) then they could have a look through the likes of Autotrader to see how many of those RS3's for sale have options like the interior design pack and give it as a percentage. I know that it's not totally accurate but would be interesting. If that was even an option in the past, I've not followed RS3 options close enough in the past to see if it was to be honest.
