Since 1989, Japanese car manufacturer Mazda have been at the forefront of the market when it comes to small, two seater cars which have generally small engines, a lack of roof and the Mazda Miata, Eunos Roadster (depending on what part of the world you are in) or as we know it the Mazda MX-5 has been a favorite to many.
The Fiat 500 has, from its launch in the late 1950’s been a super-mini with an abundance of character, however back then it may not have been classed as a super-mini, as it was, I would imagine the same size as many small cars of the era, it’s just that in recent decades cars have grown to an extent that they no longer fit in parking spaces.
