The old school maintenance thing zippyh pointed to is a good thing to use if you're going to keep the E39 longer. At 87k miles, the car's about to have a bunch of issues that should be taken care of. Belts and spark plugs are two that come to mind. Is it the 6-cylinder or the 8?
In the meantime, I have some man-made maintenance issues as it looked like someone grabbed my driver's side mirror on the E46 and broke it off --- there are finger streaks on the mirror. I just ordered a replacement housing and mirror for a really good price. If you're in the US, PM me for information on the parts place I used.
