I dont own taycans or macans. The 70k mile cayenne has been bullet proof. Those cars you keep mentioning are from 2 decades ago. Ferrari’s $600,000 V12 GTS still has the same oil leaks your 12 year old FF does.
I don't doubt some V12's have had oil leaks, but not all of them. I have 64K miles on my V12 2008 612 and 28K on my V12 2015 FF. Neither engine has leaked any oil. In fact they don't even burn enough oil between changes to need to add any. There was one exception. When I drove my 612 to Arizona and New Mexico from Massachusetts, I put on 6604 miles and did have to add 1.5 quarts during the trip. The only exposure I've had with Porsche is my wife's 2019 Panamera 4. While I don't care for some of the controls, I must say the build quality is excellent and the car has given 58K miles of trouble free driving.
You seem to be missing the point. The cars from 2 decades ago went bad when they were young = poor design. The cars which are new today also go bad (my less than 2 year old Panamera has had multiple issues) = poor design. Just because you don’t happen to own those models (Panamera, Taycan or Macan) doesn’t mean that Porsche isn’t still making poor designs. The oil leaks on the 812 engine cover occur in places which don’t exist on my FF’s engine so I have no idea what you’re talking about. Given your extensive post history, it would seem that you really do have a passion for Ferrari but can’t quite bring yourself to own one because your head rules your heart. That’s fine, we all know that Ferrari makes questionable design choices, but please don’t come on here complaining about Ferrari issues while at the same time demonstrating a blindness to Porsche’s failings. Those of us who own both brands know otherwise and it just makes you look foolish.
