We’ve been talking about used cars, and one of the most wildly known and trusted sources for used car prices is the Kelley Blue Book. The blue book was born when a family owned used car dealership would buy trade ins from dealers, using a list of used car prices they created at the dealership to inform the dealer of how much their vehicle was valued at. Their list was vast and created a reputation for the Kelley's as trusted appraisers of car prices, and they published their lists in the first Kelley Blue Book, which took its name from social registries. Many people use the Kelley Blue Book for used car pricing, but be careful when sighting it at a dealership, because you might get taken for a ride. Kelley Blue Book prices are often lower than other sources may value cars at, so you might lose out on a good amount of money if you are selling or trading in your old vehicle for another used car. And dealers have many more sources than the Kelley Blue Book, so you might also end up paying more when purchasing a used vehicle if its the only place you check for used car prices. Make sure you check multiple pricing sources, including the Yellow NADA book, before looking at used vehicles so you can be more informed and the dealer can't take advantage of you. But the Kelley Blue Book is a great place to start when trying to figure out how much you can get for trade in on a your old car and how much to pay when purchasing a used vehicle
