How interchangeable are the A3's?? I understand to get an S3 front end you have to change the bonnet to but you can keep the headlights? What about if i just wanted to change over the headlights from the new 8p3 or 8p1? is that possible or even the 8p1 ? When you look over on eBay just to get an idea of the year range it always says 03 - 08 so that would mean there all the same then? But ofcourse ebay obviously isnt the best source for information, in jap cars alot of the **** on there never fits properly lol not sure about the audi's.
