At the risk of alienating a forum that I have only just joined and will likely still need significant advice and help from, surely it is better not to add badges that were not intended to be there from the factory, but to leave things plain and OEM? After all, we are talking about a sedate and stylish Audi, not a loud-exhaust, fake-turbo popping ricer driven by a spotty youth.
When I bought my new A5, I think Audi were going through a bit of a de-badging phase and I was disappointed that mine did not say 3.0L quattro on the back, just TDi. How was I supposed to let the 2.0 TDi owners know that they were in the presence of a more expensive and powerful car with a much higher spec? But soon I came to realise that my car attracting less attention was only a good thing for so many reasons and so smug mode set in. Sure I could show them the power if needed, but better to take out out of sport and flappy paddle mode, set the radar cruise control to comform and queue up the next track on the banging B&O stereo for chill mode.
Another example: My S2 has all of the engine and interior parts from an RS2, but it is an S2, not an RS2. Therefore an A2 with however many upgrades is not an S2 (I have seen them with S2 quattro badges in the past) and if they did not leave Neckarsulm with an S-Line or Special Edition badge, why feel the need to add one.
IMHO and before I get roasted, it is always better to be the wolf in sheep's clothing (whether in terms of power or spec or class) rather than shouting about it from the hill tops as there is always something bigger, better or faster just around the corner. Much better to put it in 5th, or 6th, 7th or 8th if you have it, sit back and smile smugly to yourself that you not only own it, but know just how good it is and that the other guy is unconsciously incompetent - i.e. he is blissfully unaware of what he doesn't know and is therefore missing out on.
I do this every day that my car mad neighbour refers to my 392BHP Audi S2 as "that old Audi 80 of yours" as he boasts about how fast his MG is now or how grippy the new tires are....makes me feel SO smug that Kryten's + Clarkson's smug modes combined just aren't enough!
Cheers n fears (for the roasting)
Simon - I'll get my coat
P.S. Having written this, I realised that I own cars with 4, 5, 6, 7 & 8 gears, (of the two 4-speeds, one has OD on 2 gears and one has OD on 3 gears, one column OD and one on the gear stick). In other words, every car I own has a different number of gears changed in a different way. I guess that's 50 years of development for you but no wonder my 17 year old son is confused about gear changing in all of dad's cars!
