I've ordered a new wheel from oemvag, €447 - thanks for the recommendations.
Biker - thanks for the offer but I'm committed to the new wheel now however given the state of the roads there is a chance I might need another at some point so will get in touch if I need to. My damaged wheel was judged to be unable to repair by 2 refurb specialists, mainly due to the damage on the inside edge. Would like to turn it into a mini coffee table by glazing the top but suspect it will end up in the garage for the next 20 years!
