from what I've read, the best riding cars are the citroen ds and the Mercedes 560sel [which used a variant of the citroen hydraulic suspension technology]. I would be in hog heaven if I got to drive either one.
the citroen ds is indeed the softest ride i have ever experienced in a car. my friend's father had one ( a 1968 model) when i was a child and i rode in the back seat of it once and it was astonishing. the rear seat was mostly very soft foam rubber (with no springs inside or vinyl covering), and i sank well into it and it hugged me comfortably. as he backed out of his driveway, i could feel no rumble or bumps at all, even though his driveway was very rocky and undulating.
the downside was that it had the least powerful engine i have ever experienced in a car, and when his father selected "drive" after backing on to the road, he floored it up the shallow gradient hill, and he kept it floored all the way, and the thing just ambled along with no push or urgency at all.
i owned 2 mercedes. my first one was a 1988 500 sel, and it was a very nice car, but i soon got a 560 SEL because i always wanted one. it was vastly superior to the 500 SEL.
it was a very smooth car and it had an exceptional poise about it that made it feel "chariot" like to ride in.
one could feel how extremely heavy the car was, yet marvel in the lightness of touch it took to manoeuvre it deftly in all manner of driving dynamics. the suspension was hydro-pneumatic and was a pain to maintain because few mechanics in australia were familiar with how to service it, and the ones that were charged exorbitantly.
however the ride was as plush as a cushion in a straight line, but once even the slightest body roll came into play around a corner, the suspension would jack up the pressure on the outer side (imperceptibly except for the progressive harshening of the ride on that side of the car), and the car would maintain a level stance through the corners to a surprising degree.
acceleration was very smart, but one had to push the pedal fairly firmly even to get the car to roll slowly away, and that gave it an initial impression of gutlessness to some of my friends who drove it, but it quickly becomes apparent that further pressure on the pedal rapidly results in a flooding surge of a launch to rapid speeds, and even more pressure results in a frightening scream of the engine in an emergency power application that pushes one back hard in the seat.
the seats were rather firm and not as comfortable as others i have ridden in, but they did not cause postural fatigue after many hours of sitting in them.
here is a video that shows some of the characteristics of the cars ride (the sound is boomy due to poor recording device) in a normal "town driving" setting. disregard my chattering and forgive the graininess of the clip. i hope the clip is not jerky in motion however because that is the most important aspect of the clip. the smoothness of ride.

here is a clip of portion of a rapid drive into town which shows the cars characteristics at higher speeds. at the beginning of the clip i am going at about 40kph on a downhill ramp where upon i immediately depress the throttle to wide open for a small while before i have to repress myself and ease into the 100kph traffic in a sensible manner. i was rather late for an appointment at the time, but i nevertheless decided to film a few minutes of the trip.
(it is unfortunate that the microphone type is a condenser microphone which raises it's gain steadily in periods of silence and then makes the car sound like a hurricane is sweeping around it, but in reality it is almost totally silent inside the car except for the distant whirr of the engine when under hard acceleration.)
notice the brown car in front of me bouncing up and down in some road undulations whereas my car is only minimally affected.

after paying the toll, i set off again, this time only partially depressing the throttle (about .75 of the way) and i let the throttle off at 95 kph and then throttle up mildly again to 140 kph and idle along until i am on the straight where i press the throttle very mildly (about 1/2" (1.75cm)) and the car sidles up to about 160 kph in a languorous manner, and into town i went.

here is a flat out 0-170 kph speedo shot. i did not have any more room in front of me on that freeway to go faster.
i wish i had done some much faster clips of the car before i had to let it go.[youtube]http://www.youtube.com/watch?v=n3Lk0URbVIw&index=124&list=UUpB1H594Ek2H_hWBxJ7ja7g[/youtube]
