S3s are excruciatingly dull to look at though.
Establish what your priorities are first. If it's styling, it's got to be an Edition 30 for me personally. If you want all weather traction and better [than VW] interior quality, get the S3. If you definitely want a Golf but better made than the MK5, get the ED35.
Simples
I don't get the ED35 personally, or Sciroccos, but that's just me. Perhaps skip them and look at MK7s?
