I already did that the day I bought the car on a spreadsheet with date, part changed, cost and any mentionables. This is just a "used car" to me with styling and performance that I enjoy driving. I'm not a purest collector! If I can find a good parts at a savings over OEM parts that's what I'll do. It's a nice car that I enjoy but won't spend "gobs" of money putting expensive OEM parts if a more economical part is available.
