Ask them to supply it with the 18" alloys off the 265 instead. I reckon that would make it a better car overall.
You know, I probably would have ordered the 265 if it came in 5-door guise in the UK. Sadly it's a 3-door only for us. However, I don't think I want to cause any more delay or confusion at Seat, they seem to be struggling as it is without me adding to their list! Crossing my fingers the wheel supplier pulls their finger out.
