it says est for one, also the v6 is "est" at 3750lbs

its been said the v6 with the perf pack (heavier wheels, brakes, suspension) will be under 3500.
dont expect the gt to weigh more than 3700
the new engine weighs 10 more lbs, the new mt82 trans is suppose to be 4 less pounds than the tr3650.
at most 100lbs gain over 2010
