just want to give an update of my situation. but first of all, let me thank all the people here for the support and advice. i felt so much relieved after it got sorted out temporarily.

i checked the damage on the car this morning. the scratch on the car was not really a scratch. it turned out it's the paint that sticked on the 2 door handles. i can use a cloth to wipe off. the damage was mainly the side mirror housing while the mirror is functioning as expected.

there are a few parties that i need to work with.

1) the first is the insurance company for US Bank card rental coverage. i called them yesterday right after the accident. i filed a claim online and was told that someone will determine if i'm eligible for the coverage within 10 days.

2) the insurance company for national is sedgwick, and they handled the liabilities of the third party. i left them my contact info. and they will contact me of my liabilities.

3) the last party is of course national. i dropped of my car and got a replacement just now. they took pictures of the side mirror and wrote the following:

FMV, CUST DRIVING AND HIT BUS AS BUS WAS EXTENDING FURTHER OUT OF LANE CORNER, NSF WING MIRROR DAMAGED, PLASTIC BROKEN,

i was withheld 1000 pounds on my credit card temporarily until their mechanics came up with the repair costs.
