Market Position:
The 1999 Mazda MX-5 Miata (NB) is positioned as an accessible, fun-to-drive, lightweight sports car, renowned for its pure driving experience and affordability. It competes in the compact sports car segment against vehicles like the Toyota MR2 Spyder, Nissan 240SX (S14), and Porsche Boxster (though at a significantly lower price point).
Competitive Analysis:
The NB generation of the MX-5 Miata refined the original NA's formula with a stiffer chassis, improved aerodynamics, and a more powerful engine. The 1999 model year marked the introduction of this second generation, offering a more modern aesthetic and enhanced performance while retaining the core tenets of the Miata philosophy: a balanced chassis, rear-wheel drive, and convertible fun.
