Hi Dan,
When the struts are bad the oil is gone from the shock section. This will let the car bounce up and down after going over a bump. There is no oil in the strut to stop the motion.
Like Boone says the SVX feels hard on bumps. I find that at 30 or less the bumps can be pretty rough. However on the same road at 60 the bumps are as smooth as silk.
The suspension is stffer than on a common car but not as harsh as it can be as say on a Porche GT2.
The tire stiffness is also a factor here. A softer lower performance tire will give you a better ride. Your car may also have the stiffer front strut mounts.
It sounds like your struts are fine. You may want to check the front stableizer bar rubber bushings and make sure the bar is not rusted under the bushings. That rust can only happen if the car sat for a long time.
