1961 Lincoln Continental
Back in the late ’50s, Ford’s luxury division Lincoln was far behind Cadillac, not only in sales but also in popularity and style. Ford decided that had to change and the 1961 Lincoln Continental was born. When Lincoln showed the new model, the automotive public was stunned. The beautiful elegance of its styling, conservative use of chrome, straight lines, and futuristic design transformed the four-door luxury model into a work of modern art.
The best exterior feature was the suicide doors, with the rear doors opening toward the traffic. Of course, this wasn’t the best solution, but it only added to the charm of the Continental. Interestingly, Lincoln offered a cool-looking four-door convertible model which proved very popular and unique on the market (via How Stuff Works).
