I thought it was 04 to 05 that they changed. I have been looking t lot at them and trying to find out more info. I think I like the 02-04 the best. They have the full size rearends. The 05- have the chopped off @$$ look. I know the local bike shop here has a used 04 S3 limited edition (gloss black frame, wheels, etc.) with 1200 miles for $7000 OTD.
