i'm trying to find an S3 front bumper (along with a few others) for my 08 a3 and have been offered one but the guy bought a bumper off e-bay for his A8 and this turned up ? (coughs * bullsh1t) but whatever i want one he's got one , but it looks like an s-line one to me i got part number (8p08074378) that doesn't make any sense and he's not 100% sure. so question : whats the difference between s-line and S3 ????
