My car got branded

Tara dropped her cigarette on the backseat of my brand new car. I was so angry with her. Of course I was not nearly as angry as I should have been. How angry can you be if your best friend damages anything of your stuff? But hey! It’s my brand new car! So you can imagine how pissed I am - not about Tara but about the overall situation. I think a new cover will do if it comes to the backseat, but even that is too expencive for me right now. I was already considering if the cheap car insurance I got would cover it but I guess my deductible is too high.
