 I wrote my last review of my wagon almost 2 years ago. My car now has 55K miles and is better than ever. Since the stock suspension is very wallowy I replaced the shocks & springs @ 50K with H&R springs and Bilstein shocks from the Tire Rack. Wow, feels like driving a brand new A6. A worn CV boot was found and replaced during suspension work. Thats it, no other problems. This car had the Upsolute ECU reflash done to it over two years ago and not a single problem. It adds an extra 30HP and 50ft-lbs torque. This thing pulls like a freight train and gets 38 MPG on long trips. Replaced stock stereo which stinks with a $250 (installed!) Sony from Best Buy. Way better even w/ stock speakers.
