new to me 2001 a4

i was passed down a 2001 a4 1.8t with extremely clean interior. the only problem is it has 230,000 miles. i would like to fix the stance nothing to crazy paint it flat black and tint the windows. performance would be nice but i worry about the high mileage. all i want to do is chip it and maybe put a bigger turbo on it just enough so i can hear it. any suggestions would be awesome
