I have never traded in a car. I have thought about it and even tried on occasion. Each time the price offered would have forced me to leave too much money on the table. I have not been willing to do that, yet. I always end up selling the car myself. I have never failed to come out much better than if I had traded the car in. Typically, as might be expected much much better. Kelley Blue Book, KBB.com, say selling yourself will benefit you by about 15 to 25 percent over trading your car in. It is true when you sell a car yourself there is some time and effort involved. A lot of elbow grease is required to get a car ready to sell (though I would think to get a top trade-in offer this work would already have been done). There is also the variable of how much time it will take you to sell your car. This of course will depend on several factors. Some of which are the price range of the car (more expensive cars will likely move more slowly), where you live, and how competitively your car is priced. I wrote a post on how to sell your car in 7 Tips to Sell Your Car Fast. I would recommend if you have questions about selling your car you review this post. The key point is to know in trading in a car is how much money you are leaving on the table and what your time is worth. Is it worth your time to sell the car yourself? You should answer this question before you trade in your next car.
