StevenN Funny you mention the CF Adapter.
I recently got rear-ended, so decided to a bit of an upgrade once I get it back from the body shop.
I bought a CF-to-IDE adapter, and a 128GB memory card to try out in the system. (Not because of TRIM issues, but because it appears that the SSD's *really* don't like to work correctly at -30 to -40C)
I also wanted to join the next decade with Android Auto/Apple Carplay, so bought a Korean Adapter from Indiwork:

I'll post updated info or guides, depending on how they work, since they're currently sitting in boxes waiting for my car to return.
