Analogies aside, Audi S-cars are the Ying/Yang of the auto enthusiasts ideal automobile. Everything else will be slightly or greatly off center of what is "perfect".

Sure you can fvck a porn star (C5 'Vette), but so will have everyone else (neighbor down the road just got one, and so did your co-worker).

Or you can date a young computer science student (brand new Toyota Prius), and she probably won't ask for much (no aftermarket, drinks little gas) but she has no skill in the bed (don't even think of taking it to the track) and isn't quite nice to look at. Sure, these are both ends of the spectrum, but I still feel the Audi is in the middle of that range.

You've given your old lady (S4) all these years of your life, why not make one last investment, try to go into couples counseling (stage 3)?
