I am on my third of the body style. Started off with a 91 town car, then on to the crown vic a 94, and currently have a 96 Marquis. Their winter performance is solid. The Town Car performed better on take off in the snow and on rain surfaces than the Vic. I think that is due to the air ride suspension in the Town Car. My Marquis sets the bar on winter performance of the ones I have owned. It has the touring package combined with the air ride and that has been a real treat for getting around in poor weather conditions. I am not sure what the suspension is on the police interceptor.. If you are just looking for that body style, I would look for one with the touring package with air ride. Don't forget these are big heavy cars so they do not stop on a dime when its slick, so careful driving is a must. I have never had one whip around or slide out of control on me so they are sure footed. I have had my Vic, the one with the standard suspension, break the back tires loose and not want to hook up when it was wet and especially when it was snowing. I put a lot of miles on my cars and they are well built and easy on maintenance. I bought each of them with around 50k and got rid of the town car with 337k and the Vic with 300k. Both were still running fine and in good shape. My Marquis has 174k on it and I have not had to do anything but normal maintenance. Well except for an electrical upgrade for my stereo system. Hope my info helps out and good luck with your search for one of the big bodies from fomoco.
