"Luckily, you can easily look up your car's trade-in value online. Simply visit sites like Edmunds or Kelley Blue Book to learn about recent trade-in values for similar models within your local market. This way, you can have more realistic expectations and consequently be able to make a more informed buying decision. Market knowledge aside, keep in mind that your vehicle's condition also influences its trade-in value to a large extent. According to the Kelley Blue Book, for instance, salvaged or reconstructed used cars from New Orleans lose about 20% to 40% of their value. In any case, you can boost your chances of a higher trade-in offer by making your vehicle as clean and as presentable as possible."
