Considering a V90 R design - ride quality?

[namfreak]

Got a R Des V90 D4 on 20" wheels and I do find the ride quite firm.
But I haven't drive an Audi or BMW to compare it to

I guess I'm comparing it to my old V70 R Des on 18"

I find the V90 ride is fine on well maintained roads but as soon as you throw in patches and defects the 20" wheels will soon make them felt

Chatting to one of the techs in the dealership and he didn't think there was much difference in ride between 18 and 20"

It is a big car. 360 parking camera certainly helps

As others have said the deals on a well specced V90 R Des are hard to turn down - all those features and all too often the big wheels come as part of the deal
