how long has audi been producing this motor? and from what ive heard these 4.2 a6 2001ish, are pretty bullit proof... are they that much better than a 2.8 (gas price wise, is it worth it getting a 4.2 compared to a 2.8) and generally how expensive are the parts for the a6 with the 4.2liter?? thanks guys
