Bob Kelley, Who Made the Kelley Blue Book an Authority on Cars, Dies at 96

Bob Kelley, who turned the Kelley Blue Book, a price list published by his family’s used-car dealership, into one of the world’s leading authorities on cars, trucks, motorcycles and pretty much anything else that gets you from point A to point B, died on May 28 at his home in Indian Wells, Calif., east of Los Angeles. He was 96.

His son-in-law Charlie Vogelheim confirmed the death.

The Kelley Blue Book started in 1926 at the Kelley Kar Co., a Los Angeles dealership founded by Mr. Kelley’s father, Sidney, and an uncle, Leslie Kelley. As one of the biggest used-car dealerships in the region — and eventually the country — they had a constant need for new inventory, and the book originated as a simple list of prices that they were willing to pay for certain cars in certain conditions.

Mr. Kelley joined the company after the end of World War II, a prime time to get into the used-car business. The war had put an end to new-car production, and it would be several years before automakers could meet the demand.

He was initially in charge of both valuations on new inventory and compiling the book, and he brought a jeweler’s eye to the job. He studied all the factors that go into deciding a car’s road-worthiness and visual appeal — mileage, sound system, paint color — then developed a long list of data points that, combined, would produce a price.

“He had this habit of driving the oldest car on the lot home at night to understand why it wouldn’t sell,” Mr. Vogelheim, a former editor at Kelley Blue Book, said by phone.

Thanks to the accuracy of Mr. Kelley’s listings, and the market-setting power of his family’s business, other dealerships began using the list as well.
