I'm 18 years old and I was driving and this 72 year old man merged into my car on the highway and scratched 4 panels and dented 3 panels. I have a 2016 STI with 2300 miles and he took all the fault. I have to file a claim with my insurance and I was wondering if anyone's been in an accident before and can give me advice. I get an diminished value check since technically my car has an accident right? And does anyone know where I should get repaired at since i'm on Long Island?
