"The Mercedes-Benz S-Class has a computer-driven suspension system that reduces body roll as the vehicle whips around a corner."
Mrs. Felis' '95 Caprice has the "sport suspension." Nice thick anti-roll bars, stiff shocks, hard springs. Corners like a go-kart, and you can throttle-steer it. Plus, no computer to break...
The F-41 option. I always got it on my company Caprices, year after year. That and limited slip with snow tires in a Minnesota winter would get you most places.
