According to Media Connection, World of Cars is the world's largest printed car directory covering 1,500 makes and 4,000 models from around the globe. The guide itself is published in Poland and has been cataloging cars since 1991. This year marks the second year they've done an English language edition.
They are hoping that seeing last year's complete volume will spur sales of the guide for '07. Once you see the nearly 500-page guide, you'll understand the appeal of a thorough listing of every car on the market for that year. The company intends to offer the download only until Christmas, so act fast. Just click on this link and find the "Happy Hours! Free PDF" button to get to the 60 MB download.
