Year to Year Changes
1998 Buick Regal:
Apart from reduced-power airbags, like those on other Buick models, changes were few for 1998.
1999 Buick Regal:
Suspension modifications promised to improve ride and handling on the base LS model this year. A standard tire-inflation monitor also was installed. The normally aspirated V6 engine in the Regal LS gained 5 horsepower.
2000 Buick Regal:
A split folding rear seatback became standard. A side airbag for the driver (but not the front passenger) became standard on the Regal GS and was included with optional leather upholstery on the LS. The GS gained a body-color grille and new-look alloy wheels.
2001 Buick Regal:
General Motors' OnStar assistance system became standard instead of optional on GS, and new Joseph Abboud fashion designer packages added special paint, trim, and Gran Touring suspension.
2002 Buick Regal:
Steering-wheel radio controls were newly standard on GS models this year.
2003 Buick Regal:
Regals gain new door-pillar and roof-rail trim backed with energy-absorbing foam for head-impact protection. Antilock brakes and side airbags were made optional on some models.
2004 Buick Regal:
OnStar assistance is now standard on the '04 Regal GS.
