The first-generation Mazda MX-5 (codename NA), also known as the Miata in North America and Eunos Roadster in Japan, is an icon of automotive history. Launched in 1989, it resurrected the segment of small sports roadsters (inspired by 1960s British roadsters like the Lotus Elan) by bringing legendary Japanese reliability to it. Famous for its pop-up headlights, its featherlight weight (around 950 kg), and its Jinba Ittai philosophy (the oneness of horse and rider), the NA offers a pure, communicative, and rear-wheel-drive driving experience. Today, it is a highly sought-after collector's vehicle. Its mechanical reliability is exceptional, but its worst enemy, given its age, remains corrosion.
The Mazda MX-5 NA is a masterpiece of affordable automotive engineering. Mechanically, it's a tank disguised as a ballerina: the B6 and BP engines are almost indestructible if maintained with minimal care. However, its advanced age makes body inspection paramount. Rust is the only real reason for concern. If you find a healthy example (or one already professionally restored at the rocker panels and frame rails), go for it. Prioritize a 1.6 115 hp model (post-1991 to avoid the SNC) for original purity, or a 1.8 for more versatility and the Torsen differential.
