Heyo,
It is most likely an SS but an EX police car. If it's manual it wont have traction control at all. If you have a little isolation switch or in normal terms another "off" switch for your lights behind the steering wheel on the left, it is a police car. Another way to tell is, look at the light in the roof, is it a regular dome light or does it have 2 map reading lights in it also. More than likely it's an SS, just one that Mr officer ringed the a** out of back in the day.
