1927 LaSalle Roadster

Drop the top, and cruise like a movie star! It sounds like fun. But movie stars live in sunny California -- most of us don't. Convertibles may draw people into showrooms, but sedans take them home. In 1956, only about 2.6 percent of Chevy customers drove home in ragtops. Despite that fact, the carefree appeal of 1950s convertibles has made them a symbol of that era.

This vehicle is the oldest surviving American automobile. In the 1860s, a small steam carriage running under its own power -- without horses! -- was so startling that people paid to see it driven. It was a curiosity, not transportation. By the time its inventor, Sylvester Roper, died in 1896, new innovators were transforming horseless carriages from curiosities into practical vehicles.

This 1858 Rogers steam locomotive is typical of those used in the United States in the second half of the 19th century. Its flexible wheel arrangement, high power output, and light weight were well suited to the tight curves, steep grades, and hastily constructed track that characterized American railroads. This locomotive struck an agreeable balance between practicality, safety, and economy.

Luxury cars offered the greatest in comfort and the latest in technology. They also provided status -- a large part of their attraction. Builders like Rolls-Royce specialized in extravagant cars with corresponding prices, while mass-market manufacturers like General Motors and Ford offered Cadillacs and Lincolns for customers of more modest means. Sport sedans and SUVs may have replaced carriage-inspired Victoria bodies, but luxury still sells.
