The funny thing Matt is the SS's are suppose to have lighter components. Namely the hood, but I do not think they weigh the fully optioned cars. I think a SS minus all the options would be what GM advertises.. I took my CD changer out and put it on the scale and that thing weighs 20lbs.. Spare and Jack totalled 35lbs.. I hear the rear seats and seatbelts together is close to 50lbs weight savings.. I personally like listening to CD's.. It would be just my luck to get a flat and I like to take people for a ride.. So all those things stay in the car...
