Ford Motor Co (F) unveiled the Mustang more than 50 years ago, and even though sales in the U.S. have lost their momentum, overseas demand has boomed, AP reported.

The Mustang became the best-selling sports car in the world last year, with more than 150,000 sold. It beat out sleeker competitors, including Bayer Motoren Werk's (BMWYY) BMW 4 Series and Porsche's (POAHY) 911 model, to win the title.

Sales in the U.S. dropped 13% in 2016 and are down 29% so far this year. But the car's sales shot up 40% in China during the first half of 2017 and haven't run out of gas.

The most recent iteration of the iconic car was built to appeal to buyers the world over. It can be customized with right-hand or left-hand driving, its air conditioning system was built for Middle Eastern sands and its front end meets European pedestrian-safety regulations.

"It's democratic. A working-class person can drive this car to the plant, and a banker can drive it to the office. You can't do that with a Mercedes [Daimler AG (DDAIF) ]," University of Dayton professor John Heitmann said. A basic model with a V6 engine starts at $25,000. The Shelby GT350 with a V8 costs about double.

Mustang clubs exist across the globe from the 12,000-member Mustang Club of America to the 200-member Icelandic Mustang Club. The Mustang will hit markets for the first time this year in Brazil, Ivory Coast and Palau.

Here's a look at the Mustang through the years with insight from Car and Driver.
