It's strange on BMW's part - why send a big cheese from Bracknell to be in Leeds for 9am on Xmas eve, after they file a defence. As I said to the Cust Service Manager - it will cost them more than the wheels to send him. And yes, I wont let the wheels out of my sight, they are my property after all. I have a few ideas what might happen, but as ever I'll assume Big Bro BMW is reading so happy Xmas BMW.
And the point about the validity of doing a run out test on cracked wheels, so bleeding obvious but never occured to me its fundamentally floored.
