Thank you for your response Gareth - I think you got the source of my dilemma right - I was really looking for some comfort blanket of reassurance 😉 Sometimes a good discussion can help with the "sat on the fence" position as it can gently prod you in one way or another..
What was not making it easy was that I could not see any up-to-date photos showing what the cloth interior would look like in real life ( you can hardly rely on the 3d rendered images on the Audi site) and I was also not sure if the puny sound from the demonstrator speakers was a result of these not being yet bedded in..
In the end I went with the leather option (Atlas beige) rather than the comfort and sound package - time will tell if I will be happy with my decision
Thanks
Martin
