I wouldn't say it's a radical change at all. What are we talking about.... a couple of bumpers, a spoiler, some skirts. How many people (including a lot of audi owners) would see an A3 with an S3 bodykit with no S3 badges and think it's an S3??? Not many, I would think. I reckon most would only think... "that's a nice looking A3". Pretty much the same as they think when they see a real S3. I bet most people out there couldn't even identify an S3, S-line, etc just by the bodykit. I know that before joining this site I couldn't. Sometimes it's still not obvious.
