A new car depreciates quickly during its first nine months or so, which means that a person looking to keep their car new and have the least amount of finance charges should make sure they trade in their new car quickly to avoid a large loss being made on a sale or trade in value. Of course, maintaining a new vehicle is often the best choice for those who wish to maintain their warranty and service options as complete into the future. The warranty for most modern cars lasts for around five years, which means this is often the point where people look for a trade in or sale to maintain their warranty on a vehicle they own.It is important to know what the current value of your vehicle is at all times, which can mean doing some research into the price and availability of vehicles on the market. This means that a large number of vehicles offered at a discounted price that may be reaching the end of their warranty or finance period entering the car market lowers prices for current owners and should mean a vehicle is placed onto the market early for sale or trade in.

For others who own vehicles, the choice of when it is time to sell their car comes down simply to the point where the car becomes too expensive to keep running. This can mean that a large number of expensive repairs need to be completed, which may be more expensive than the cost of a new vehicle would be. As cars age and lose some of their fuel economy they can often become expensive to run in terms of has usage. When daily running costs become too expensive, it can mean the time has come to find a new car that is less expensive to run.
