Even the Astra VXR has a heated SW option!!
Which (to be honest) is the only other car I am considering. Although with the paint problems they are having on the only colour I would consider (Arden Blue) I am still steering towards the GTI. I am in the lucky position of being able to buy tax free, which makes a vanilla build VXR £2k cheaper than the GTI - however I feel the GTI residuals, build quality (although the new VXR is miles ahead of my Mk1 VXR) and running costs will win me over in the end!
