Hi all !I am about to get a 2003 E39 520i 2.2. Just want to make sure that I am aware of the running cost in maintaining this beauty Can someone give me an indication of how much I am expected to spend on maintiaining a E39, especially one which is 5 years old with a mileage of 80K ? I heard a lot of feedback from friends and secondhand car salesman, stating that there are quite a bit of Wear and Tear items that need to be changed regularly to avoid major repairs. Can someone tell me what are those and how frequent should they be changed and how much they cost ?Sorry if all these info have been posted somewhere in this forum before Any feedback / comment is most appreciated !Thanks !
