I have a 1992 Taurus ex-police car. The grille and the dual exhaust are the only external differences between the regular and police taurus. The police taurus uses the SHO susupension and sway bars. The motor is a 3.8L with some differences internally, different ECM, and the transaxle is unique with a 3.73 final drive ratio. This gives the car great get up and go around town and the suspension being from the SHO gives it good handling too. Inside there is a police certified 140 mph speedometer. Options for the interior are rubber floor covering, vinyl seats either front and rear or just rear. Mine came with carpet and cloth seats but I've since added the rubber floor covering. There was a gauge option too in place of the coin tray. Before converting your Taurus or SHO to look like a police taurus it would be much better to buy an ex-police car used. I bought mine in AZ off ebay for $1200 (ex-supervisor car no lights on roof, solid color) and it came in great shape. They had done really good maintenence on it. I suggest checking ebay for taurus (police,cop) just copy that in the search box. They are on there all the time and that includes solid color cars with no lights on the roof. If I had the room I'd buy another, they are fun cars, decently fast around town with a lot of low end torque, great SHO handling, and a lot less maintenance than a SHO. I have done nothing to mine except put in a starter since Dec 2003
