5: Mazda Miata
The Mazda Miata was one of the first lightweight roadsters on the market. Mazda was going for something fun and lightweight. There have been quite a few Mazda Miata models over the last few decades. The overall design of the Miata is iconic for being lightweight and nimble.

Mazda hasn’t swayed far from this formula in a few decades, but there also hasn’t been a lot of innovation. The Miata could have been much more with a few enhancements. Mazda has stuck to the same formula for a good reason. However, with a little bit of design and innovation, the Miata could have been a more landmark sports car.
