Ask for full payment?

Someone drove their electric scooter on the street into my parked car and shattered both the rear window and the small quarter window behind the rear passenger seat.

He was kind enough to ring my doorbell, apologize, and provided his contact info. Repair came out to about $900 but my insurance is covering the remaining amount after my $500 deductible.

The guy is being very cooperative and willing to pay, but he did make a comment about getting paid every two weeks and “he’ll figure it out”. I’m doing alright financially, so this amount is not fully debilitating or detrimental, but it’s still not ideal for my situation at this moment.

I know people are having a hard time financially, so I don’t want to put this guy in a tough position, but I also don’t feel like I should be responsible for the bill on this.

What’s a reasonable ask?? Should I ask for the full $500 or take the loss on a portion of it and let him pay me less? He could’ve easily not come to my door and just left the scene, so I also want to somewhat reward his honesty…
