Car stationery in front had a newly qualified driver in but no P plates, junction was clear , she went to go but then for some unknown reason slammed her brakes on. I went into the back of her I was also stationery before this so not at great speed - I know I am at fault. There was barely any damage to her car (took photo), a tiny panel on the back looked like it had very slightly popped out, but nothing more. My car came off worse with a smashed numberplate and silver trim at front cracked off. We exchanged details, her mom has just left a voicemail to say they've took it to a garage and the bumpers been damaged and theres paint and scuff marks so shes asked me for a call back so she can talk through the quote or she will just go through insurance....what would you do in this circumstance?! I'm shocked as there was no damage to her bumper that I could see or can see now in the photo and no scratches either...how do I know shes being legit. I'm so stressed I have NO money to pay for this but I guess I'll have to suck it up...
