Not sure I totally agree with old cars being rock hard with poor damping. I guess it is how old you go back. I have a 1998 306 GTi-6, a 2003 206 GTi 180, a 2005 Alfa GT 3.2 V6 which all are sporty cars. All with brilliantly compliant rides. I can remember my first car was a 1984 MK1 Astra 1300S and yes not a sporty car but had great ride. My friend has the GTE and it was again comfortable and not rock hard.
The E55K's I had were worlds apart in the comfort stakes and I have had an SL60 and SL55 that were both very comfortable without rock hard rides.
I agree cars are getting faster, safer and higher performance in many areas. Does that make them better? No, not in my book at all. Of course better is subjective but in my world no.....I have no desire to look at cars newer than a certain age now. I don't want keyless, touch screen complex cars and many don't. It adds weight and complexity to no improvement to the car or driving experience. Just creates an anodyne Playstation car. If I want that I'll jump on a Playstation.
