I have a 2001 740i with 170k miles, and am the second owner. When I purchased the vehicle from a BMW dealership, it had some minor hazing on one window. It now has moderate hazing on all side windows. Is this something I could expect BMW to resolve? If so, what is the procedure/process? If not, is there a source, at reasonable cost, to get replacement windows. At the current rate of hazing, in six months I will have a serious visibility problem.
