The 1984 Toyota Celica was slightly restyled from the previous model year. The front end was redesigned, this time with the true pop-up headlights that were on its cousin, the Toyota Supra. The '84 Celica also got a new hood, grille, side vents, and taillights.

The 1984 Celica was available as a coupe or a hatchback. The coupe was available as a base-level ST, the midlevel GT or the sporty GT-S. The hatchback was available as a GT or GT-S. The 2.4-liter engine got a slight increase in horsepower, from 96 to 105. Gas mileage was about 26-38 mpg.

The 1984 Celica was much loved for its peppiness, although once off the line it tends to accelerate slowly. Drivers also speak highly of the GT-S's super comfortable seats. These cars are popular for racing due to their excellent cornering ability, although most enthusiasts say they require modifications to make them fast enough. Rust tends to be a problem, particularly in snowy climates were the roads are salted. Resale value tends to be very high.
