i bet my m30 has like 50lbs of it in there, i heard that luxury cars have more for deadening road noises.
i weighed my car this week at the local recycling and dump center.
listed, my car weighs 3300 lbs.
i took out all the rear trunk panneling, spare tire and jack stuff, rear seats both upper and lower and trunk to cabin sound damper ( its this 5 lb rubber piece that goed behind my rear seats)
i got on the scale and it weighed 3380 with myself inside the vehicle.
note i also had 50 lbs of tools in a toolbox. stock seats on this car weigh a ton becasue they are electric.
i need MAX seats and take out sound deadning. maybe i can luck up for a 3100 lb m:)
