hey ive never owned an Audi but I have found one that I am thinking about getting. Its a 99 Audi Quattro RS4, 52k miles, Twin Turbo, 6speed...and so on. It is currently sitting in a field for unknown reasons. It will need a front bumper/passenger fender and passenger door. I am just wondering if there is anything i should watch out for and about what one MIGHT cost (i know this one would be hard to say for sure) Reps for help. Thanks
