Right now I'm torn between keeping my new E63 and reselling it to buy an E92. I want to make the V10 work, but I've heard horror stories of unmaintained E63's being nightmares to their owners' wallets. What would a maintenance checklist look like considering the following?

A) What preventative maintenance I should do right away (Rod bearings, Fluids, etc) to prevent expensive problems down the road

B) What extra maintenance I should do to keep the car running perfectly (So I can avoid worrying about something randomly breaking)

C) The most common problems that E63 owners have to fix (So I can replace these parts/ remedy the issue before It happens)

D) What "restorative" maintenance is most important?
