That's unbelieveable!
In such a case, I guess I'd put the car into a river and never ever even consider a BMW
again.
What you describe does not seem to be normal. Here we had one case where the leather
of the seat was ripped of from the seat after 6000 km, but it's been repaired by the dealer.
Do you have sport seats?
For images, maybe you should have a look at some of the user pages of BMW drivers.
Another chance would be going to mobile.de or autoscout24.de and look up used E65,
in many cases, there will also be pictures of the interiours of those cars.
