Absolutely yes. Get a PPI to avoid issues with your friend. From a good Porsche mechanic. Main thing you’re looking at is the overrev report (aka the DME report). It will show if it’s been misshifted or how long it’s been past redline. For reference I sold my 987.2S with over 100k miles for $30k and I thought that was a little low

You can’t fit golf clubs in a cayenne? I detest golf but that seems strange. Adults fit in the back seat relatively comfortably and the cayenne was super helpful when we just moved. Fits a lot with back seats down, I would guess I could fit at least 4 sets of golf clubs if I had to. It also tows my race car like a champ plus all the gear I could realistically use in the trunk. Is it an F150 or Yukon XL no but it doesn’t handle like those tanks either. But I came from a cayman.

I have very similar setup and use a direct burial rated cat6 cable. Works great. No reason to use MoCA. I do have a ubiquiti surge protector on the end before going into the house, and have it grounded. In the garage I have a PoE switch that powers an AP and security camera
