James,
Just like what else has been said I would check the W210 forum and use the search for most of your answers..
For #1 I would not believe that story unless the rear seals have been proven to function and repel water effectively.
For #2 this is an indication that the window has been replaced and the window was not properly adjusted as needed. This would never make it from the factory that way so I would check for damage from an accident but the window has definitely been replaced..
Good luck.
