Is Kelly Blue Book Accurate When Selling a Car Privately?

The question arises frequently among car owners: is the value provided by Kelly Blue Book (KBB) accurate when selling a car privately, or is it better to trade it in at a dealership?

Firstly, it's important to note that many individuals are likely to undervalue their own cars due to a lack of expertise in car appraisal. This is because the nuances of the automobile market are often complex and require a deep understanding of various factors such as market trends, regional variations, and personal market bias.

While Kelly Blue Book is a widely recognized source for determining a car’s value, it is not the sole arbiter. Other valuation guides such as NADA Blue Book, The Black Book, Edmunds, and others exist to provide a broader perspective. However, these guides often differ from each other due to regional variations and market nuances.

Understanding Market Bias

Market bias, often seen in agricultural commodities and other distinct markets, can also affect used car prices. Let's explore this concept further.

Consider the example of agricultural commodities, such as corn and soybeans. In my current location, prices for these commodities are influenced by the CBOT Chicago Board of Trade price. The CBOT price represents the cost of a commodity delivered to Chicago. Prices in my region are then adjusted based on the cost of transportation and the local market bias.

For instance, some farms and bio-refinery plants in my area actually have a positive bias on corn, soybeans, and DDG (dried distillers grain), meaning they expect to pay above the CBOT price due to regional preferences and local demand. Conversely, another company I worked with had different plant pricing based on export sales from the Gulf of Mexico ports, highlighting the impact of regional and export markets on pricing.

Applying Market Bias to Used Car Values

Now, let’s apply this concept to used car prices. Using the example of a 2019 Mustang Convertible, the car's value can vary significantly based on location and timing.

For example, in December, a Mustang Convertible in Miami may be worth more than the same car in Sault Ste. Marie, Michigan, or Duluth, Minnesota. This is due to factors such as the holiday season, where people are preparing for Christmas, and the general increase in consumer spending.

By early January, snowbirds, who have migrated to warmer climates for the winter, begin to arrive. These individuals often seek stylish convertibles for the season. However, a major event in the Villages during New Year's impacts the market, as seniors buy convertibles for the big bowl game, further increasing the car's value.

In this scenario, the perceived value of the car can change rapidly based on market conditions and local biases. This can lead to discrepancies between the KBB valuation and the actual market value.

How to Determine Your Car's True Value

To accurately determine your car's value, consider the following methods:

Compare Multiple Valuation Sources: Use Kelly Blue Book, NADA Blue Book, The Black Book, and Edmunds to get a more comprehensive view. Compare the average values from different sources. Check Local Market Trends: Look at recent sales data in your local area. Pay attention to regional variations and market biases. Seek Professional Appraisal: Consider hiring a professional appraiser to conduct a thorough evaluation of your car. They can provide a more accurate and reliable valuation. Consult Dealers: Dealerships often have access to real-time market data and can provide insights into the current market value of your car.

In conclusion, while Kelly Blue Book can provide a useful starting point, it is important to consider the local market and regional biases when making a decision about your car's value. By combining multiple sources of information and seeking professional advice, you can make an informed decision that best reflects the true worth of your vehicle.
