I'm in the process of looking for a car. Anyways, I'm considering many brands, but there are a few brands I would like to know a bit more about from people who have owned them. Specifically, Audi, BMW and Volkswagen. I won't be buying new or anything 2005 and up sadly. If you have owned or own an Audi, BMW or Volkswagen, could you speak a bit about the maintenance costs, especially the oil change costs? Any additional comments including year, model and where you get them serviced would help me greatly. Thank you.
