You must work in an urban detachment Manny... I think the Impala is a superior PC in a built up area(city), but the 300HP Caprice is second to none for highway patrol in rural Alberta. I was talking to a Mountie who was in a chase with his Caprice LT-1 "slick"(sans light-bar)... he had it up to 270kph. I don't know why GM stopped making those PC's.
And I ALSO don't like the Ford Crown Vic... in the winter, the back end feels so loose it feels like your towing a trailer. The range on those things was sad too. You had to fill it up twice/shift. Compare that to the 90 litres the Caprice can hold(80L tank/10L reserve).
