Let's take a trip down the memory lane to celebrate the world's best-selling roadster.

The Mazda MX-5 Miata has celebrated its 30th birthday and with its celebration comes an orange serialized 30th Anniversary Edition that's limited to just 3,000 units worldwide. It's indeed a great run for the Miata, but did you know that there was a competition between Mazda design teams in 1983 with the aim to produce a lightweight, inexpensive sports car? 

Moreover, several concepts came out in between the four generations of the MX-5, some materialized while some, unfortunately, was left to oblivion. Browse through these slides and get a glimpse of the history of the world's best-selling roadster.
