Oh how things have changed! Just take a jaguar XJ from 2 decades ago or just sit ( without driving ) in a peugeot 504/604 with cloth seats. Back in the days comfort was a sales argument. Cars had loong suspension travel ( speedbumps how do you mean), and seats were truly sofa like. Tires? 60 or 65 at 13 or 14 inch. And then things changed. All had to be sports, sporty, nurburgring tested and so on. In came short stiff springs sport seats, 35 tyres all to keep weight transfer under control when negotiating a corner at 100mph. The nurburgring is the worst thing that ever happened to car industry .My old 2cv s were a joy to drive, my golf mark 1 had suspension travel to the moon and back, my 504 was just incredible as was my citroen bx. I am ONLY talking about comfort of course. Anyway, which car company, which model is now marketing their brand or car as comfortable? It would not sell, even a 2500 kg SUV needs to be "sport" to do the school run.
Which leads to the next question; Which new car is truly comfortable? ( LS 400 not allowed!)
