New for 1999: The Lumina remains primarily unchanged for the 1999 model year, with a new
  exterior color being the only addition. 

  History: Introduced as a 1990 model in 1989, the Lumina is Chevrolet's version of General  Motors' GM-10 midsize car platform. A thorough redesign for 1995 resulted in a quieter, stiffer  body structure and improved interior ergonomics. Nearly three-quarters of Lumina buyers are  married, and Chevrolet reports that half of Lumina buyers cited the car's very attractive price as  the primary reason for their choice. The Lumina occupies the top rung of Chevy's sedan ladder  since the departure of the Caprice full-size sedan at the end of 1996. In 1998 Chevrolet added  the optional OnStar system, an advanced mobile communications package that combines  cellular phone and Global Positioning Satellite (GPS) technologies.   Model years: 1990-94, 95-98 

  Trim Details: The 1999 Chevrolet Lumina is available in three trims: Lumina (base), LS, and
  LTZ. Safety features include dual airbags, child safety locks, daytime running lights and an
  anti-lock brake system (ABS), which is optional on the base model. A 3.1-liter
  160-horsepower V6 engine is standard on the base and LS, while the LTZ upgrades to a
  200-horsepower 3.8-liter V6. Standard features include air conditioning, power door locks, a
  theft-deterrent system, a tilt steering wheel and an AM/FM stereo. The LS upgrades with a
  stereo cassette system, cruise control and power windows. The sporty LTZ adds a rear
  spoiler, 16-inch aluminum wheels and unique front and rear fascias.
