i own a 2000 a6 with 240,000 miles on it. but she runs like a dream. new belts all new control arms. i want to mod her out but dont want to invest in a car with this kind of mileage. im trying to decide on window tint, a pioneer sub and amp to go along with the bose system, a motorized radio headdeck , or led strips on the fog light holders. what do you guys think?
