The B6 S4 series is not my favorite. More pedestrian than the following B7, more bloated than the preceding B5, and not even close to matching the sex appeal of the newest B8, passing B6s usually makes me sigh in disappointment, wishing it were any other S4. It takes a whole lot of “doing it right” to get me excited about one. Luckily, our seller today did it as right as one can with a B6, checking all the right boxes to take this 2004 S4 from bland suburbanite to badass sleeper.
[X] Avant [X] 6-speed [X] thoughtful performance upgrades [X] BBS CH
From the seller (who sounds like my kind of car guy):
Up for sale is my 2004 Audi S4 Avant (wagon). This is one of the few with the 6speed manual transmission. If you’re not set on whether or not you want an S4 Avant, let me give you a bit of a sales pitch on it. First off, the wagons are cool. I know that’s not much of a sales pitch, but they look far more modern than the sedans, hold their values so much better, and simply make more sense. Unfortunately, they didn’t sell many. So getting your hands on one can be tedious if you have any other prerequisites.
So what makes these cars cool? Well, they are all wheel drive sports cars with high revving V8s that happen to hold 5 people and all their luggage. They sound AMAZING too, especially set up like mine. Audi’s interior quality is second to none too, and mine has been babied. All the window switches feel as if new still.
What makes MINE special is this:
It’s been meticulously maintained, and we’ve got the service records to show. Also, it has a good list of upgrades that allow for higher power and torque, as well as better fuel economy. The car is making somewhere around 400HP now, and has an incredible amount of torque too. All work has been done by European Auto Garage in Knoxville, TN.

I love it. For the first time ever, it’s B6-ness almost enhances it, putting it just low enough under the radar that the de-resonated near-RS4 power can suckerpunch unsuspecting passers by. The owner has taken extremely good care of it, not abusing it like so many other “STAGE 11 S4” tuners for sale on eBay. This is a stealth family-hauling hammer, the best the B6 can be. With about 90k miles on it, this is a great deal if it stays under $20k.
