There are several good threads on this topic on this forum. They go into superb detail on everything you need to know on how to set-up the suspension of a GTV. Reading through them you will realize that there is more than one way to possibly get the ride dynamics you desire.
I have found that the factory original spring rates, dampeners, and tires are hard to beat for a comfortable ride. It can also be the least expensive set-up to install. Replacing everything that can wear in the suspension system in one go with OEM spec parts is also the fastest way of getting a baseline. The last time I did this, buying all parts from Classic Alfa in the Summer of 2016 cost me circa $600 (original style dampeners, standard springs, rubber bushings, etc.) for the parts.
Nothing is more confusing than trying to figure out, for instance, a dampener's contribution to ride quality when the bushings have perished. I found that I need a part's performance specifications and me doing actual road testing of a set-up to make any sense of each set-up. Paying a shop to measure spring rates and dampener rebound rates is for me, money well spent.
You are right to think that these cars should both look good and be fun to drive.
I find that renewing the rubber bushings in my GTVs every 30 to 40 thousand miles always restores that "new car ride".
It took me a few years of fitting different rate springs, bushings, dampeners, and tires then driving each over under different conditions before I decided what my preferred set-up in a road-only GTV with none or one adult passenger. But that is probably just me, who likes to understand what my options are. Plus, I'm indecisive.
PS: if you truly get into it, once you successfully complete the exercise of setting up your GTV's suspension this should make complete sense (if it doesn't already)
text from Koni's web page:
"Tuning Tips of your car suspension
If the car rolls on the rear outside suspension during corner exit, increase rebound damping force on the front inside. The front inside suspension affects the car mostly on corner exit. By adding rebound damping you will loosen the car up on corner exit.
If the car rolls on the front outside during corner entry, increase rebound damping on the rear inside suspension.
By adding rebound damping to the front on both sides equally, it will tighten the car some. By adding rebound damping to the rear on both sides equally, it will loosen the car up some.
Note that the shock absorbers do not change the amount of weight transfer, only the time it takes to transfer this weight.
Only adjust enough rebound into each shock absorber to eliminate the undesirable characteristic. Adjusting too much rebound may mask a handling problem of another sort and may even make things worse and dangerous."
