You should inspect the outside of your vehicle at regular intervals, looking for dents and noticeable scratches (25mm and over in length). You should also check all glass for cracks or chips, and for any damage to the wheel or the trim. If you encounter any damage, consider correcting it as quickly as possible so it doesn't get any worse.
For small areas of damage such as scratches, chips and dents, a SMART (small and medium area repair technique) repair may be more appropriate. However, before you organise for any maintenance work to be carried out, it is important you speak to your finance provider to determine whether approval is required.
