Those after a small, fun-to-drive sports car should instantly place the Mazda MX-5 on their shortlist. It's the best-selling roadster in the world, and for good reason. Through all of its generations, it's remained true to the same ethos – low weight, low power, rear-wheel drive, compact dimensions and maximum fun.
It's also had a fabric roof for most of its life, with only the third-generation car receiving a folding hard-top as standard. However, the current fourth-generation model goes one step further, with a whole standalone hard-top model named the RF.
