^^that's the max load rating...the car at stock height, without the back struts compressing, is supposed to tow 4100lbs.
You can't go off the weight of the car since it's almost impossible for your car to have the same tires it did when it left the factory AND the dealer. You have to inflate them to the spec on the tires themselves.
Heh my cam weighs around 3300lbs. '94 LE 4 door. At least that's what it said on the last emissions test (although at the time, my heavy ass subs were in my trunk and I think they counted the weight of the driver doing the test).
