Well, I for one am very happy with my Eos and happy to say so! With regard to the ride, everyone who owns a car has bought the right to speak their opinion about it, so I respect everyones thoughts on this. My own perspective is that it all depends on context. I didn't buy the Eos as a 'cruiser', and assessed the ride quality during my test drive. I bought the 'sport' model too, for roadholding ability. I would never describe the ride, therefore, as brilliant - it is exactly what I expected it to be based on why I bought the car. Perhaps other peoples feelings about this relate more to their own perspective within the equation 'expectations before buying car/actual conditions after purchase'.
Nonetheless I'm not blind either - as a seasoned Audi owner some of the plastics lower down in the cabin are hard and definitely not quality, and the roof creaking, which I also sometimes get, suggests the complexity of the roof works against it - the sunroof is a nice touch but I suggest comes at a cost! I would have lived without it, personally, if it simplified the roof, and I do like simple solutions - they tend to work longer and be more trouble-free!
But - at the end of the day I love my car because its different [bet Clarkson drives a Bimmer, says it all really!], I love the top down driving [I really do!], and without being flashy most people I know have passed a comment on it along the lines of 'cool' - which my Audi never did!
