Many features that were on the standard equipment list for 2002 have been deemed optional, or deleted altogether, for the 2003 model. Deleted items are speed variable power-assisted steering, which is being downgraded to a nonspeed dependent system, and heated outside rearview mirrors. Side-impact airbags are now optional instead of standard (and continue to be available with leather seating surfaces only), as is a rear split-folding seat. Safety also comes with a separate price tag, as antilock brakes and traction control are now options on the lower Regal LS, but together with a tire inflation monitor, remain standard on the more upscale GS model.

On the upside, all Regals receive an improved starter for cold weather cranking, and a new impact-absorbent headliner, plus two new packages to help Regal buyers group options for a better price. The new Luxury Package includes dual-zone climate control, illuminated visor mirrors, auto-dimming inside and outside rearview mirrors, AM/FM stereo with both cassette and CD player and steering wheel-mounted audio controls. The simpler Leather and Wheel Package includes leather seats, a split-folding rear seat and 15-inch aluminum wheels.
