I''m looking to buy a 2000 S4 that is kinda local to me. The thing is I don''t know which shop or dealer to take it to to have it checked out before I buy it. The seller says they will gather paper work, which to me means that they haven''t really serviced the car much(hope I''m wrong). I'm new to Audi's so any help will be great. I have read on the forums for trouble spots, but I think a good mechanic is needed for the job. Thanks
