Original used Toyota as benchmark. Regal matched Toyota w/o paying the premium. Have owned GS and LS. (98&99) Love the supercharger but it has added to service costs. 2X CD failures in factory radio. Change oil every 3K and service transmission + filter change every 2 years and this car will get you down the road in comfort plus tight handling (GS). LS fast enough just have to stomp on gas to get the performance. Electric Windows are the biggest weakness. I just lost my GS to freakish but major engine fire. Something shorted at firewall after my daughter got home from church. Even with freakish engine fire will likely replace this with another Regal.
Radio/Cd controls on sterring wheel
Very weak fragile cup holder design! Cup holders have broken on both my Regals. Have to wedge my coffee mug next to my hip. Needs stronger window glass clips. Can't repair and very expensive to replace whole unit.
