Those of you who had the E53 will remember the famous door handles that peeled all the time. They really seemed bothered by sunscreen for some reason. I went through a few of them.

So far my E70 has been defect free on the interior (knock on wood). Still have a "loose" tailgate and went through a few fuel pumps, but it has been perfect the last 20K miles (outside of ditching the bleeping run flats)
