Rennlist seems to have the most active Cayenne forum these days.

My 2011 turbo has been pretty reliable but there are the maintenance costs and mine’s about due for another high pressure fuel pump.

My recommendation is to buy a CPO Cayenne from a Porsche dealer. Mine had a fueling issue when I bought it and if I had to pay repair costs it would have been substantial since Porsche didn’t solve the problem until the 3rd repair. They ended up replacing the high and low pressure fuel pumps and the fuel control board.
