If you have a brand new car then you will probably be aware that it loses quite a chunk of its value as soon as it is driven off the forecourt, meaning if you went to sell it a week after you bought it, you are likely to get quite a bit less than you paid.
With this in mind, it is vital that you look after your car to ensure that you can retain as much of its value as possible. Cosmetic damage can quickly devalue a car and can put potential buyers off. If paintwork is damaged and there are scratches that go through to the bare metal then this could also rust. It is advised that you get any paint work or body damage repaired as soon as possible and by a professional, reputable company as bad paint jobs can look as bad as the damage.
It is also important to look after the car mechanically, such as keeping up with services and checking levels etc.
