Generally, the price we pay for junk cars are based on several factors. The four main ones are: Year, Make, Model and Condition of the vehicle. In most instances, if the car is truly junk then we determine the value based on the weight and other metal values. The weight of your car in tons will vary depending on the make, model, year, materials and type whether it is a sedan, SUV or truck. The weight of the car is useful when trying to sell your junk car for cash. Most junk cars have already reached the end of their operational life and will be stripped of recyclable parts and then crushed. It is not unusual to assume that we sometimes may pay based on the condition of the car but in many situations we are required to pay based on weight and the metals the same as our competitors.
