Overview

The 1991 Toyota Supra is a rear-wheel-drive, two-door sport coupe from the third-generation Supra (A70/Mk3), positioned as Toyota’s flagship performance grand tourer of the era. It’s ideal for drivers who want a classic Japanese sports car with a strong tuning community, comfortable highway manners, and a distinctive 1990s wedge styling. In the early 1990s market it competed with cars like the Nissan 300ZX and Mazda RX-7, offering a blend of straight-line power and long-distance usability. Today, it’s sought after as a collectible and as a project platform, especially in Turbo trim.
