I can't believe it I actually pulled the trigger on a car that I love rather than an appliance car! And it was a car I never expected to love as much as I do. I was looking at GTI's and 335i's. I just bought a 2007 Audi S4 sedan with about 56,000 miles on it, and its in impeccable condition. It has the grey Alcantara seats and the Bose Symphony stereo. I was just wondering what things I should be aware of with this car being that I am a noob and didn't really do my homework on it, as I was expecting to buy a BMW 335i. I absolutely love the style of this car inside and out. I'm not planning on modding it in anyway at the moment, however I would like to know if there are secrets to making the key open the sunroof and things of that nature. I may switch out the Bose Symphony stereo for something that will have navigation and and a USB port so I can play mp3's from a thumb drive or hard drive. I already read your noob FAQ post but it appears to answer questions about the S4 with the turbo 6 cylinder. Any help would be appreciated thanks, and I'll post pics later.

 

Congrats on the purchase!

I've no real input as I'm looking for one myself. I have a 2001 A6 4.2 and a 2001 TT and so far have had good luck with both.
My theory with performance oriented cars is that they need to be well maintained; and if you thrash them a lot, things will break.

Enjoy your purchase, and good luck.
