not that it is going to happen anytime soon, but in another 100,000 miles or so i'm sure it'll be time to rebuild the motor and tranny in the car. so rebuild it or how hard would it be to upgrade to a 30valve v6?? would I need to swap the computer or should I just scrap it all at that point and buy a new audi that already has the 30valve. I really wanna drive this car til it won't even stay together tho.
