If the accident is not your fault its the other guys insurance that is paying for it so it shouldnt matter what you have or havent done to the car.
We been through this before... umm... let's say ur car is not registered, and it gets in an accident (other persons fault) their insurance company will find whatever reason NOT to pay fo your car to get fixed - so i THINK it does matter what has been done to your car.
Thats right, we were talking about not engineering cars and getting into an accident where we you not at fault.
