Thanks for the words of support. I have checked with all 3 metro dealers and the results are:

1) We'll fix it.
2) It depends - we have to inspect it first & get factory approval, then we might or might not do the repair.
3) Why did you call the other 2 dealers? We were waiting for you to ask us after we told you it cost $1000, but it will still need to go up the chain of command.

I am now wondering if she should have gotten the 528i instead of the C280?
