Just a little bit of news for anyone interested, I've been badgering a company in the UK about fitted sun shades for the X1. They have finally put then on their list as available for the X1 (I've been pestering them since March).
The company is Van Style UK, price for a set of 6 is £95.99 (a lot cheaper than BMW in France or the UK) and they ship internationally.
I haven't ordered yet as I'm just about to go away but will do very soon.
I've added a link so anyone can take a look and see what you think
