Re: I need your opinions...
in response to one of your issues... the headlight fogging.... are you talking about a visible moisture inside the headlamp assembly, or simply a "foggy" headlight with a film on the outer plastic...
as for moisture issue i cannot say that i have a convenient and easy remedy for it, however if it is just a film on the outside of the headlamp the do in fact make a product specifically designed to renew old headlights. check autozone or napa if that is the issue.
the rattling when the window is down may be coming from a loosening of the bolts that hold the window to the motor. thus when it is up, it is secured against the seal of the window and does not audibly rattle. but when the window is in the door it has no seal to press against and therefore rattles. this is a somewhat easy fix if this is the problem. all it would consist of is removing the door panel and, with the window up, tightening the bolts holdin the window to the motor... generally a 10mm nut i believe.
