The investment you make in your vehicle is always gratefully returned by that vehicle. When you take care of your car, it takes care of you. Most people are aware of regular maintenance routines, such as the need for frequent oil changes and fluid checks. What people often forget about and neglect is how much the car's physical appearance plays in the value of the vehicle. If you let your paint and interior appearance deteriorate, it's going to affect how much your car is worth drastically.
