Well besides regular oil and filter changes, I too have put on a new AC compressor, plug wires, brake pads, and before we left for AK in 2013, I did replace all rubber hoses and fuel lines and the serpentine belt. Took all of the old rubber with me in a box just for my own supply of emergency parts just in case. I have not had manifold issues, but have had to replace donut gaskets between manifold and tail pipe a couple of times.
Thanks for the replies, but right now still looks like I am the mileage leader with the exception of the 494K mileage unit brought in for auction.
