The Oldsmobile Alero is a compact car that was produced by the American automaker Oldsmobile from 1998 to 2004. The Alero was introduced in spring 1998 as a 1999 model to replace the Achieva and Cutlass. The Alero went into production in April 1998. All Aleros were built in Lansing, Michigan. The Alero was Oldsmobile's last compact car as well as the last vehicle sold under the brand. Production ended in April 2004 along with the entire Oldsmobile brand. The Alero was sold either as a 4-door sedan or as a 2-door coupe. It shared its chassis and many parts, including engines, with the Pontiac Grand Am, the other compact N body 4-door sedans. 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. The Alero experienced minimal changes during its 5-year run. Most of these changes were either in choice of engines or options. In 2003, the Alero's daytime running lights were changed from high-beam to low-beam. The Alero was also sold in select countries in Europe and in Israel between 1999 and 2001 as the Chevrolet Alero, and was only available as a sedan. However, the O4 concept was unveiled a few weeks after General Motors announced that they would be phasing out the Oldsmobile brand, meaning that production possibilities of the O4 would never be realized. Because of this, a second generation Alero was never built and the car was phased out with the Oldsmobile brand in 2004.
