I'm new here to the site and have a question for you guys and gals. I recently received my 2013 825i the other day. I bought it with the poly roof, glass front windshield, and poly rear panel with a sliding window. I use my gator to check irrigation wells so I do a lot of driving on gravel roads. After driving it for a few days I noticed that the dust is pretty bad inside the cab. I can tell that the dust gets sucked in and hangs there. I was wondering if I would take off the rear panel, if that would solve my problem or make it worse. Does anyone else have this issue and if so how did you fix it?
