Once your car is in a mechanical state to be sold, you will need to ensure that the exterior of the car is attractive. You will probably need to take photos of the car from the outside and the inside to place into adverts.
You may want to sell your car online, on sites such as Auto Trader, or you may want to post it around your local community. However you choose to advertise your car, it is important that you make the outside and inside of the car as attractive as possible.
It is surprising how much a good clean can spruce up the look of the car. First start with the inside of the car, make sure that you clean the whole dashboard, as dust can build up very easily. Chuck out any of the rubbish that you have hiding in any nooks and crannies of your car, such as in door side pockets and in the backs of the driver and passenger seat. Give your car a good hoover from the inside, and try to sweep up any hairs. If you have had a pet in the car, you will find that there are lots of pet hairs across all of the upholstery, so make sure that you look under seats in your cleanup. If you have children, you may want to remove any child's seat as this will make the back of the car look a lot bigger.
As for the outside of the car, make sure that you invest in some good polishes so that you can really bring the paintwork out in a shine. Brands such as Meguiars are good for shining the paintwork. If there are any small dents or scratches in the car, you can easily buy some scratch remover which can help to rub out many of the minor scratches on the exterior.
