<human>: This is a throw away account.. Basically, I had rented a rental car through Thrifty car rental to travel to see my significant other's family so I wouldn't have to put the wear and tear on my own car. As we were driving home in the evening, I went to change lanes from the leftmost lane to the center lane and when I did, my back tire picked up something on the road. 

I didn't even see what I ran over, but what ever I did hit got sucked up in the back passenger side wheel-well and flopped around in there till just before I had a chance to pull over to see what it was. The damage done was a lot of black scuffs around the wheel well, along the back passenger side door, the door handle had been ripped off, and the back wheel had a hole in it.

I had filed a claim with my insurance company, but I wasn't covered for this kind of incident and my back up (my credit card) didn't provide rental insurance, so now I'm left with the bill of about $3000. That is a big bit of change for me and Thrifty expect it to be paid back in 6 months which I'm not sure if I'm capable of. I called Thrifty and spoke with them shortly, and the basic jist of them was I had to pay and the only amount they could knock off was about $300 for the 9 day "out-of-service" fee.

So what can I do? I'm not trying to get out of this fully, I opted out of the insurance they provided without my own and something happened, but a little more off would help a lot! Also, I feel like $3000 is a bit much for the repairs that had to be done.. I want to get an itemized list of the repairs so I can take it to my own guys and get estimates. 

Anyways any advice would help a lot, thanks reddit!
