Where To Weigh My Car

Your local landfill

If they are not busy, the highway commercial vehicle enforcement facility (highway scales)

I have seen roadside scales in Oregon that are on all the time, even when the police isn't flagging vehicles in.

As mentioned, bathroom scales, typical digital scale goes to 300, you would need a 4:1 lever (4' plank, wheel set 3' from scale).
I did this with a body shell, put the whole car on block the height of the scale assembly and just moved the one scale around.
If you are careful in placing the car on the scales this could probably be more accurate than drive on scales with their 20lb increments.
