Hello. Someone backed into my car and crumbled my passenger door and scratching it all the way down. Their insurance considered it a loss and is going to give my car an r title if I decide to keep it. The problem is they are not being fair to me. I have receipts for parts for the car and proof it’s in my car and has been on my car. These include spark plugs and vapor canisters and a master and slave clutch cylinder and brand new tires. They are telling me everything I have done to the car other than tires is maintenance or preference and they are not gonna pay for it. I have $3500 in parts and labor for stereo and aftermarket performance parts. They want to give me $2700 if i keep the car or $3100 if they take it. Can I fight this at all to get more money for am I screwed? I own a 2003 Nissan Sentra spec v ser
