Mazda MX-5 Miata (NA)
1990–1997 USDM • 1.6 / 1.8 DOHC • Front-Engine Roadster
Overview
The NA Miata revived the lightweight, affordable roadster after the British and Italian classics that inspired it had faded away. With a front-engine/rear-drive layout, near 50:50 balance, low mass, and a precise short-throw shifter, it prioritized feel over outright power — a formula so successful it became the best-selling two-seat sports car in history.
