ARRGG Can't believe it , check it out:

Would they fit an S3? I thought not due the PCD being incorrect? I could be wrong though.

If they do fit an S3 then I might have to make sneaky bid :)
 
If they are off of an A4 i think the PCD will be wrong.
 
thanks god they weren't 18"s for a S3 ....would be gutted from Bristol otherwise!
