Big cars need lovin too.I looked up the specs and it appears you're correct actually...Lincolns have always been heavy cars though.
2013 Lincoln MKZ sedan weight (AWD V6): 4148 lb
2013 Audi S5 weight: 3895 lb
2014 BMW 435i : 3527 lb
I agree with the diet, I mean weighing in at that much might hurt the bank when you consider the wight it has to haul around and how much gas it burns. Can't believe it's over 4,000 lbs.
