Introduced in this form way back in 1982, the popular Camaro came in both hatchback coupe and convertible form--the latter added during '87. Base and performance-oriented IROC-Z editions were on sale in 1990. By 1990, all Camaros had a driver-side airbag. New standard equipment included a tilt steering wheel, tinted glass, intermittent wipers, and halogen headlamps. The high-performance IROC-Z convertible gained a standard limited-slip differential and new 16-inch alloy wheels, but those items were optional on the IROC-Z coupe. The '90 dashboard flaunted new yellow-gauge graphics, further enhancing the car's assertive nature.
