Would be great if I could get some opinions as to who is at fault? Pics below.
Edit: The owner of the car offered me numerous times that he would call it even if I paid him the money for repairs and he wouldn't go to his insurer. Is there any reason why he would do this? Not too familiar with car insurance, but it seemed a bit strange offer?
This is where his car was parked:

The damage to his car:

Another view of the garage door - he was parked behind the white car on the right:

Here's a view of the garage door opened - his car scrapped the door while it was open in this position:

A view of the parking bay he was in - is this considered a proper park since it doesn't have a line on the left hand side?

Thanks in advance!
