I agree they are just stunning cars to drive..and I have a C6 RS6 as well. However the S8 just feels so much better built, the quality of the materials used...leather and plastics all feel superior...I feel it may be because the D2 was the last Audi to be produced by engineers rather than accountants
Having said all that the ballistic power the RS6 delivers is also very addictive
and never fails to impress me, just a pity the build quality is not up there with the D2
