i had a 2008 335i before my m3 and that thing ran great when it ran, but when it broke it BROKE. lol i was always in a rental, at least 3-4 times a month for about 4 months, when finally i got pissed and called bmw financial and went back n for with them for another month, when they finally agreed to buy it back ( before they bought it back they offered me a check for $5k for my time and trouble, which i said no to since it will probably continue to break down) they faxed me over an agreement stating they will buy it back, i did have to buy new tires since mine were almost bald, but i got the new tires went to the dealer, met with a rep and he inspected the car, and i signed off and walked away...then got buried in a new m3... lmao.
if u finance with audi, call them and dispute it, if its paid free n clear or through another finance co, get a lemon law attorney.
