^my weekender needed nothing for the first 70k miles. Most reliable car ever owned.

Then the streak came to and end in a hurry. I looked at all my bills once when I went over the $13k mark. Cost of parts was about 2/3's the money spent. On one invoice for repairs which included tires and wheel straightening among many other things for about $5k, the labor was only 25%. And even if you DIY $4k of that total $13k was the IMS/RMS/FW which is not worth saving on the labor to DIY given the risks.
Additionally you have to factor in the cost of tools, space and time which are not free. But the big thing is the cost of parts. even though we have online shopping and ebay that hasn't really kept Porsche parts from being expensive given their far from stellar durability.

The more miles the more addictive and costly the habit. But last time it went in for repairs I had the shakes and night terrors from midengine withdrawal.
