I have my A6 Avant posted for sale on Tucson Craigslist. http://tucson.craigslist.org/cto/2935333858.html
I tried to post every little thing I can think about the car, so it may sound a lot worse than it actually is.
In addition to the car, I also have a large majority of the parts that are needed to convert it to a 5-Speed. I have a transmission, rear differential, pedal assy, clutch master and slave, shifter assy, brand new in the box clutch kit, plus the controller and some wiring for rear diff lock. I will offer all the conversion parts to the buyer of the car for an additional $500.
