Long story short I was stupid and backed into another car in my apartment parking lot. The other car had minor damage and I offered to pay to fix it but they didnt say anything because they were here illegally and didn't want to report it to the insurance company.
Anyway...
I looked at the damage on the outside and I cant determine how bad it is as I have very little knowlege of body work. Then I pulled away the trim on the inside and found this...

Looks like a previous accident, the repairwork looks bad but I have no clue.

This is the outside damage, looks bad to me but again I really dont know what im looking at.

So how bad is it?
Going to be expensive to repair?
