Damage to a car could be caused by an owner not taking care of a car, an accident on the road or by general wear and tear. You could have minor damage which impacts the value of your car, such as stains to seats, small scratches to the bodywork or a chip in your windscreen. On the other hand, your car could have major damage from a collision which has resulted in the structural or mechanical elements of the car being significantly damaged, which will impact the value more.
