Did you know that the price of the same car can vary considerably?

That's because factors such as odometer reading, equipment and colour can directly impact the value of cars. With so many variables, it’s difficult to know the right price to pay for a car.

Bringing almost 90 years of experience in creating vehicle valuations to consumers in the U.S., Kelley Blue Book is here to build a product that helps you understand price and have more confidence in buying a car.

Experience The Kelley Blue Book® Brand

Kelley Blue Book began in the U.S. in 1918 when Les Kelley started the Kelley Kar company. After years of successfully running the car company, Les Kelley introduced the Kelley Blue Book in 1926.

Les Kelley was so successful at selling cars that he constantly needed more cars for his lot; he began distributing a list of automobiles he wanted to purchase with the prices he was willing to pay for them to dealers and banks.

Soon, the automotive community trusted his judgement as a good reflection of current values. Other dealers and banks requested the list for their use, and the Kelley name became the most trusted for car values. This list later became known as the Kelley Blue Book.

Kelley Kar company founded

In 1918, a young man named Les Kelley parked three Model T Fords in an open lot, put USD $50 in the till and started the Kelley Kar Company. It was to become the largest dealership in the world and, along the way, spawn a need for placing values on used and even new cars, known as Blue Book® values.


Kelley Blue Book® published in 1926
