Thank you so much for your reply Ken !
The previous owner of the car kind of abused it, and now it feels like the body is not properly sitting on the chassis. just feels a bit loose and unstable. I have changed the front and rear shocks and springs which has made the ride a bit closer to normal, but still it does NOT feel nowhere near as close as the 2008 superb I also own...it's that bad that on a gravel road, at night, you can literally see the headlights shaking as there would be no cushion between them and the road surface. Any ideas why this could be? Car has a tow bar mounted and it does look like it's been used a lot, so I'm just wondering what else I could do to improve as much as possible the ride quality.
Thanks again !!
