I've been searching the forum and owner's manual for developing a 10-year look ahead maintenance master plan for my 2002 Z8. In the spirit that feedback is a gift, I share this proposal with the Chat Room board before considering posting a generic version on the open forum.
A couple of my own comments. The original owner of my car apparently never used the cloth rear window protector, and in my case I plan to replace the scratched plastic window in 2012. The transmission and differential oil changes on a biannual cycle feels a bit too frequent, but since that was one of the recommendations in the 10-year fluid thread it continues. The battery was replaced in 2011, and this reset the 5-year cycle.
