How does SC400'ride compare with LS400?

[moonunit]

Hi,

I decided to buy a low mileage SC400 after driving the 1997 LS400 my mother has, but it seems there is a vibration in the drivetrain. I had the tire balance checked, but still has some mild vibration that neither my daughter nor her husband noticed. I have a new transmission mount on order, so hopefully that will fix it.

If the SC400 is running perfectly, other than lower height and stiffer suspension, should they be equally smooth and quiet?

I would appreciate owners of both cars, either current or former, to give me their take on it.

Thanks
