Oh, I just made a joke!
And even if one gets it serious one has to take in mind the car has a certified empty weight of 2155 kg (this includes the full gas tank and a driver at 75 kg). If I don't err that has to be multiplied by 2.6792 for lb so that would be 5.774 lb which is quite heavy IMHO.
See above, 2155 kg. The S 65 AMG is 2220 kg.
That is my last info (which I can not say if it is really true)
Someone will fill that gap later I think.
