I know the feeling. After months of trawling Ebay and on some occasions being messed about by traders such as Vwaudiusedspares and even worse by some con artist in Wolverhampton who didnât even know the tailgate he was selling for £100 had an S-Line spoiler (when I struck a deal and informed him he then claimed he couldnât find the tailgate and re-advertised it for £150). I did come close to buying a spoiler from a German company called Hofele but the price was fairly close the price of an S-Line/S3 spolier from an Audi dealer, so in the end I bought it from Audi. It cost just over £230 and comes primered but before it could be fitted to my car two lugs designed for fixing to an S-Line/S3 had to be cut off.
When I took it to a local body shop for painting and fitting the owner congratulated me on getting an original and said a few weeks earlier he had a similar request to paint and fit a copy made from fibreglass and he said it was a poor fit.
If you have patience you may be able to strike up a deal with VWandudispares as they did originally agree to sell me the spoiler off this tailgate for £100. But be warned they do um and ah and mess you about.

Then there is the Mick Taker from Wolverhampton. He has mysteriously found this tailgate again, check out the revision on 12th Sept, that is when I informed him it had an S-Line spoiler. Disreputable sort in my opinion but if you want to take a chance here is the link

Or maybe you would be interested in this impressive looking model from Hofele Design in Germany. I very nearly bought this for £180 inc delivery and postage.
