I reversed into someones car this weekend. The rear bumper on my car has a dent in it and a small split where the crash bar behind has pierced through it plus all the paint on the bumper has cracked like eggshell effect? Loads of tiny hairline cracks allover the paint. Its a 2002 3 door focus st170 with 110k on clocks. Basically needs a new bumper and paint. Would they repair it or write it off? If it was written off how much would i get back on it? Ta
