The 1930s might have been the greatest 10-year period in the history of the American automobile. Even in the face of a suffocating Depression, American cars continued to evolve with beautiful, streamlined designs that had never been seen before. General Motors began "face lifting" its vehicles with new styles for every model year. Hard-rubber rides were softened by balloon tires, impressive 16-cylinder engines began showing up under massive hoods and hydraulic brakes became the norm. The synchromesh transmission, independent suspension, heaters and radios made automotive journeys more comfortable than ever. It was truly a decade of advancement and achievement for U.S. car makers. In Just '30s, the publisher of Old Cars Weekly and OldCarsReport.com Price Guide celebrates this fabulous decade with a look back at the cars, and car companies, that gave us such great memories.
