My E53 porn album is here

I keep pics of my projects and key schematic images and such there.
In Notes on my Mac (iCloud) I have an E53 note with a running history of VIN, PNs for routine maintenance parts, links to awesome DIYs and particularly helpful tips I glean from this forum.
I do this for each of my vehicles so finding and re-posting things like: "What speakers did you use in your upgrade?" are easy to snip and re-post.
Works for my OCD-ness........
LOL
