Oldsmobile Alero Concept
The design of the Alero was originally previewed in 1997 with the Alero Alpha concept car, a V6-powered sport coupe that featured many design elements seen in the production Alero as well as some that were never meant for production.
The Alero was sold either as a 4-door sedan or as a 2-door coupé. It shared its chassis and many parts, including engines, with the Pontiac Grand Am, the other compact N body sedan. All Aleros came in base GX, mid-level GL, or high-end GLS trim; GL trim was split into three levels: 1, 2, and 3.
