To Herbert.. This info come in very handy as I am too contemplating to get an used e60 within this year. No doubt, used unit will tends to worry us regarding on it's maintenance costs and problem issues. But from your point of view, as an owner, those issues mentioned above are consider as mostly wear and tear parts and need a little more attention to find out, after bought it in and drive for some times before it become more appearance. Thanks again for the insight info.
